which part the first blank is asking which function to use to find the height
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
part 1 i think its cosine
 one year ago

DecartBest ResponseYou've already chosen the best response.1
if yo are using cos(50)=x/90
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
yes that's what i did
 one year ago

Cos 50 degrees is 0.6428
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
The cosine of a 50° angle is 57.9 is this right for the second part
 one year ago

DecartBest ResponseYou've already chosen the best response.1
all the trig functions are is a relationship between the lengths of sides if you divide two known sides and take that data it represents and angle.
 one year ago

DecartBest ResponseYou've already chosen the best response.1
so like radar has said the cosine of 50 is .6428 so the sides divided are also .6428
 one year ago

DecartBest ResponseYou've already chosen the best response.1
57.8 is the height of the tower because you multiplied the hypotenuse by the cosine to find x
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so it will be .6428x.6428
 one year ago

radarBest ResponseYou've already chosen the best response.0
Cos is the adjacent side divided by the hypotenusel.
 one year ago

DecartBest ResponseYou've already chosen the best response.1
what happens if you divide the side x by the side of 90
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
adjacemt side is x right and hypotenusel is 90
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
that's what i got
 one year ago

DecartBest ResponseYou've already chosen the best response.1
roughly the same as the cosine for 50 degrees
 one year ago

DecartBest ResponseYou've already chosen the best response.1
that is what we have so far
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so it would be 57.9
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so x side is 57.9
 one year ago

radarBest ResponseYou've already chosen the best response.0
when angle was 50 degrees

The cosine of a 50° angle is .6422 right
 one year ago

DecartBest ResponseYou've already chosen the best response.1
the first question only wanted to know that you would use the cosine function to find x
 one year ago

DecartBest ResponseYou've already chosen the best response.1
the next blank wants you to input the cosine of 50 which you have .6422
 one year ago

DecartBest ResponseYou've already chosen the best response.1
yes if you type in cos50 in your calculator that is what you get
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
this represents the value created when length ____ is divided by ____ feet.
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so what about this one
 one year ago

DecartBest ResponseYou've already chosen the best response.1
if you look at the funtion you know that it is x divided by the 90 feet if you divide the value you got for x by 90 it is about the same as cos 50
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
when length is 50 is divided by x feet right
 one year ago

DecartBest ResponseYou've already chosen the best response.1
no 50 is the angle you want the height of the tower divided by the lenght of the decline which is 90
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
when length is 90 divided by x feet
 one year ago

DecartBest ResponseYou've already chosen the best response.1
see how it is lenght x divided by 90 feet
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
ok i see now x/90
 one year ago

DecartBest ResponseYou've already chosen the best response.1
that is a balanced equation if you divide that you get the same value as you did when you input cos of 50 into your calculator
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
If the angle of declination changed to 60°, the cosine would be 0.5; now the length of x would be ________ feet.
 one year ago

DecartBest ResponseYou've already chosen the best response.1
use the same equation with the cos of 60 instead
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so its gonna be cos(60)=x/90
 one year ago

DecartBest ResponseYou've already chosen the best response.1
\[\cos(60^{0})=\frac{ x }{ 90ft }\]
 one year ago

DecartBest ResponseYou've already chosen the best response.1
so now you need to solve for x
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so it would be 45
 one year ago

DecartBest ResponseYou've already chosen the best response.1
yes one more blank left
 one year ago

DecartBest ResponseYou've already chosen the best response.1
there is two ways to solve for this but you are suppose to use a trig function
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
If the angle of declination changed to 60°, the angle of inclination would be _____ degrees.
 one year ago

DecartBest ResponseYou've already chosen the best response.1
no it wants to know the angle of inclination which is the angle from the bottom
 one year ago

DecartBest ResponseYou've already chosen the best response.1
the angel theta is unknown do you know which trig function to use to solve it
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so theta is 60 degrees right
 one year ago

DecartBest ResponseYou've already chosen the best response.1
if you look at the trig functions there are sin=opposite / hypotenuse cos which we covered and tangent = opposite / adjacent
 one year ago

DecartBest ResponseYou've already chosen the best response.1
so you want to use the sine function
 one year ago

radarBest ResponseYou've already chosen the best response.0
From reading the problem, I believe you could solve simply from the fact you are working with a right triangle, and the sum of the two acute angles equals 90 degrees.
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so apposite side is 45 right
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
so we trying to find the bottom right
 one year ago

DecartBest ResponseYou've already chosen the best response.1
on your calculator you push the 2nd button then 45/90
 one year ago

DecartBest ResponseYou've already chosen the best response.1
you need the inverse sine of .5 which is 2nd sin .5
 one year ago

DecartBest ResponseYou've already chosen the best response.1
are you using a ti calculator
 one year ago

DecartBest ResponseYou've already chosen the best response.1
you need to look for \[\sin ^{1}\]
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
you press sin ^1
 one year ago

Claire4christBest ResponseYou've already chosen the best response.0
yes its sin^(1)
 one year ago

DecartBest ResponseYou've already chosen the best response.1
yes what do you get when you put that in
 one year ago

DecartBest ResponseYou've already chosen the best response.1
.5 is what you get when you do the division without the sine function I am not sure what your calculator is doing
 one year ago

DecartBest ResponseYou've already chosen the best response.1
when you get the true inverse sine you will get 30 degrees
 one year ago

DecartBest ResponseYou've already chosen the best response.1
that is correct know do you notice that the 30 you got and the 60 degree other angle add up to 90 and the right angle is also 90 every triangle has 180 degrees in it so you could have just found the missing amount from 180
