Help!!!

[Katelyn Kinman]

I have a geometry quiz tommorow at school. It's on 30-60-90, P.T., and 45-45-90. I don't feel super confident with it. Any ideas for studying? Also if you use P.T with a right triangle with a hypotenuse of 3x side a with 10 and side b with 2x what is x?:-?

I suppose you know Pythagorus's Theorem - use it.

Write out the PT.
