Question

A right triangle has one angle that measures 69º. What is the measure of the other acute

angle?

Answer 1

21°

Explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°
