[FMMurphy]

A tree is y feet tall. The angle of the elevation from a point x feet from the center of the base of the tree to the top of the tree is theta. In terms of x and theta, what is y? (The tree is standing bottom to top at the right angle of a triangle).

The possible answers are

a) x tan(theta)
b) x/ tan(theta)
c) x sin(theta)
d) x/ sin(theta)
e) x cos(theta)

what trig ratio is \(\displaystyle \L \frac{y}{x}\)?

I'm sorry I don't understand what you're asking. I am a parent who has never had Trig in her LIFE!

 

[skeeter]

why then are you doing problems that you have no clue about?

what do you hope to gain from someone just providing the "answers"?

I recommend you seek out websites dealing with right triangle trigonometry and educate yourself.

So you're studying for the SAT...? It might be worth your while to investigate taking a class through a test-prep centre in your local area. In that way, you will gain the necessary direct instruction on the topics you seek.

Good luck!
