Finding angles in a right triangle
Is there a formula to use to determine the other two angles in a right triangle? The only thing coming to mind is the pythagorean theorem. I've been out of the math realm from school for awhile...(Giggle)

All I'm looking for is a hint to get me started.

Thx,

The sum of other two angles will be 90 degrees.there individual measurement depends upon the measurement of the sides.Knowing them you can easily apply trigonometry for angle calculations.

log(xy)
or just simply use sin, cos, tan functions...

$\text {In triangle } \triangle\text {ABC, where c is a hypotenuse, cos}\alpha=\frac {a}{c}\text{.}$
