A right triangle has one angle that measures 80°. What is the measure of the other acute angle?

In a right triangle, the sum of the angles is always 180°. One angle is 90° (the right angle), and since you have another angle measuring 80°, you can find the measure of the other acute angle by using the following calculation:

1. Start with the sum of the angles: 180°.
2. Subtract the right angle (90°) and the given acute angle (80°):

( 180° – 90° – 80° = 10° ).

So, the measure of the other acute angle is 10°.

In a right triangle, the sum of the angles is always 180°. Since one angle is 90° (the right angle) and another angle measures 80°, we can find the measure of the third angle by subtracting the sum of the known angles from 180°.

The calculation is as follows:

1. Sum of known angles = 90° + 80° = 170°
2. Measure of the other acute angle = 180° – 170° = 10°

So, the measure of the other acute angle is 10°.
