How to find the angle of a right triangle. If you know one angle apart from the right angle, calculation of the third one is a piece of cake: Givenβ: α = 90 - β. Givenα: β = 90 - α. However, if only two sides of a triangle are given, finding the angles of a right triangle requires applying some basic trigonometric functions:
