Question

The triangles below are similar. In each triangle there is a 53 degrees angle and a right angle. What is the measure of the third angle in each triangle?

Triangle J K L. Angle K is 90 degrees and angle L is 53 degrees. Triangle Y X Z. Angle Y is 53 degrees and angle X is 90 degrees.
37º
47º
53º
127º

Answer 1

Sum of angles in a triangle = 180°. Each triangle has angles 90° and 53°, so the third angle = 180° − 90° − 53° = 37°.

Answer: 37º.
