One angle of a right triangle measures 25°. What is the measure of the other acute angle?

65 degrees

Step-by-step explanation:

180 - 90 - 25 = 65

65°

Step-by-step explanation:

If you add all the angles in a triangle, they equal 180°. You can subtract given angles to find missing angles.

Let's first subtract 25° from 180°. 180° - 25° = 155°.

This is a right triangle, so we know there is also a 90° angle. Also subtract this. 155° - 90° = 65°.

We are left with 65°. This is the measure of the third angle.

The triangle's angles are, 25°; 90°; 65°
