Question

If sin y°=7 over q and tan y°=7 over r, what is the value of cos y°?

Answer 1

this is the figure they provided but where did they get the q and r? and 7 for that matter? I am confused....

Answer 2

make triangle relations. sin = opposite/hypotenuse, tan=opposite/adjacent, cos=adjacent/hypotenuse. So:By that, cos y = r/q

Answer 3

that makes so much more sense why couldnt they have done that??

Answer 4

they want to see you analyze the side relationships of trig functions.

Answer 5

trig is no joke!

Answer 6

thank you for showing me that it helped a lot
