In a triangle, the sum of the angles is always 180°. In a right triangle, one of the angles is 90°.

Given that one angle is 36° and the other angle is 90°, you can find the third angle by following these steps:

  1. Add the measures of the known angles: \( 90° + 36° = 126° \)

  2. Subtract this sum from 180° to find the measure of the third angle: \( 180° - 126° = 54° \)

So, the measure of the third angle is 54°.

Therefore, the correct response is: 54°.
