How do you find the hypotenuse of a right triangle when you have 2 angles (1 being the 90 degrees since it is a right triangle)
stiks02 [169]
Find the length of the hypotenuse by using either "sine" or "cosine". 

Sine= Length of opposite side/ Hypotenuse

Cosine= Length of adjacent side/ Hypotenuse

In order to use one of these, it depends on which angle they give you other than 90 degrees.
