Question

One angle of a right triangle measures 9°. What is the measure of the other acute angle?

Answer 1

x = 61°

Explanation:

A right triangle has one 90° angle and other acute angles

so that the one angle would be 90°

Also, a triangle has the sum of the interior angle 180°

= 90° + 9 ° + x = 180°

= 99° + x = 180°

= x = 180° - 99°

x = 61°

The measure of the other acute angle would be 61°.
