There are 3 sides to a right triangle.
if you pick one of the angles (but not the 90 degree angle)
you can label the 3 sides.  That is the first thing to learn how to do.

anonymous · Answer

would it be C ? (: @phi

phi · Answer

How did you get that ?

anonymous · Answer

Sine Function: 
sin(θ) = Opposite / Hypotenuse 

Cosine Function: 
cos(θ) = Adjacent / Hypotenuse 

Tangent Function: 
tan(θ) = Opposite / Adjacent 

just plugged them in the right places. the answer would be D, sorry
