You have 2 angles. You know that the sum of the angles of a triangle are =180 so what is the measure of the unknown angle Z
Have you started using sin/cos yet?
yeah i have
Okay So for this we're going to use 50degrees, x and 35
wait 50 degrees? you mean 48?
x is opposite 52 degrees and 35 is adjacent 52 degrees, got that much?
oh okay yes
So which trig function deals with opposite and adjacent?
yes And to get x by itself what do you have to do?
multiply each side by 35 and so 35tan(52)=x
Are you expected to have a numerical answer, and if so do you have access to a graphing calculator to solve that?
it says round to the nearest two decimal places
Yes, thats right
and on my calculator i get 44.79795713 so i rounded it to 44.80 is that right?
Not a problem, if you have any more, tag me.
can you helo with another one?
i do @Audeezy
this time solve for z. cant i just add together the given angles sp 90+47 and then subtract that from 180?
so then z=43 degrees
Yes because you know the triangle is =180 and the 90deg angle is given aswell as 47
Yes, 180-90-47=43 :)
alright, so do you know what angle an angle of elevation is?
a or b
are you given any values?
Well the question is: A lamp casts a shadow of a man standing ten feet away from the lamp post the shadow is 7 feet long the angle of elevation from the tip of the shadow of the lamp is 50 degrees. To the nearest foot the lampost is how tall?
Let me try to draw and tell me if I properly represented i t
my problem is i dont know what an angle of elevation is
tan(50)=man/7 man=7tan(50) and man= how tall he is .
Throw that in a calculator and see if it matches with an answer
wait so it would be tan(50)=x/7 multiply both sides by 7 and then 7tan(50)=x right?
Think so, I belive that makes him 8.3~ feet tall
wow so x=8.34 feet that a tall man!
Is it open answer?
Are you doing problems out of a textbook?
oh we are finding the height of the lamp post! much better lol. I am doing a test but it is open notes and I had things similar on my notes but i always like to check and make sure i am doing it right ya know?
Dont put down an answer yet, let me run through my math one more time
@cutiecomittee123 still with me?
wow yeah, darn it i already answered this sucks, luckily i can redo it though
Can you change your answer, ior retake it as a whole
but that would make more sense because ou have to keep in mind the shadow of the man also adds into the horizontal length
i have to retake the whle thing sadly
ahh, sorry about that
