Answer 1

@iPwnBunnies can u help me?

Answer 2

Ok, we're sorta adding to the trig stuff. Not necessarily going backwards.
Remember, I told you the tangent of an angle is opposite/adjacent.
So, you're given the legs, and the final answer 4. Solve for x. :3

Answer 3

so 9+4?

Answer 4

Err, not quite. Looking at the triangle, what would the tangent of C be?

Answer 5

im soo confused...

Answer 6

D?

Answer 7

.-. What.

Answer 8

im sorry i have no clue D:.. this is the last time i choose to help my sister with her homewrok /.\

Answer 9

Oh my. .-.
Remember, tangent of an angle is opposite side over adjacent side.
So tan(C) = 9/x = 4
Solve for x. :3
