cos (135\degree)=

sin (720\degree)=

REVIEW: Solving Right Triangles

The rest of the questions review SOH CAH TOA (triangles NOT on the unit circle).

Remember to use these ratios to find side lengths:

null

And remember all the angles in a triangle add to 180\degree.

**make sure your calculator is in degree mode**

The optional video below goes through an example similar to #31-36.
