Question

The measure of one of the acute angles in a right triangle is 42 1/3 . What is the measure of the other acute angle in the triangle?

Answer 1

Explanation: The sum of the measure of the internal angles of any triangle is 180o . In a right angled triangle, one angle will be 90o . Since we know the measure of one of the other acute (less than 90o ) angles, we subtract the sum of the two known angles from 180 to calculate the measure of the other acute angle.
