see how it is lenght x divided by 90 feet
 2 years ago

Claire4christ Group TitleBest ResponseYou've already chosen the best response.0
ok i see now x/90
 2 years ago

Decart Group TitleBest 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
 2 years ago

Claire4christ Group TitleBest 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.
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
use the same equation with the cos of 60 instead
 2 years ago

Claire4christ Group TitleBest ResponseYou've already chosen the best response.0
so its gonna be cos(60)=x/90
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
\[\cos(60^{0})=\frac{ x }{ 90ft }\]
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
so now you need to solve for x
 2 years ago

Claire4christ Group TitleBest ResponseYou've already chosen the best response.0
so it would be 45
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
yes one more blank left

Claire4christ Group TitleBest ResponseYou've already chosen the best response.0
and than 45/90
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
is that a button
 2 years ago

Claire4christ Group TitleBest ResponseYou've already chosen the best response.0
yes its sin^(1)
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
yes what do you get when you put that in
 2 years ago

Decart Group TitleBest 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
 2 years ago

Decart Group TitleBest ResponseYou've already chosen the best response.1
when you get the true inverse sine you will get 30 degrees
 2 years ago

Claire4christ Group TitleBest ResponseYou've already chosen the best response.0
i got 30
 2 years ago

Decart Group TitleBest 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
