Besides the 90° angle measure, what are the other two angle measures of a right triangle with side lengths 5, 12, and 13? Round to the nearest degree.

The longest side, 13, is the hypotenuse, so the triangle is right-angled. The acute angle opposite the side of length 5 is sin⁻¹(5/13) ≈ 23°, and the other acute angle is 90° − 23° ≈ 67°; therefore, the angles are 23° and 67°.
