Today I hope I will learn to solve a right triangle but now I only know 1 angle (the right angle) and 2 sides (not the hypotenuse). How do I establish the other 2 angles?

Help please.

Thank you,

Mike.

You know two sides, a and b. Compute the third side length with c^2 = a^2 + b^2. Then use

a/c = sin A

b/c = sin B = cos A

to solve for the two angles. You can use either a sine table or an arcsine table.
