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°**.
