The sum of the measures of the two angles is 155°.
One of the angles is a right angle.
The measure of neither angle is more than 75°.
The measures of the other angles must be 105° too.
The measure of one of the other angles equals 75°.
The measure of one of the other angles must be 45°.

Answer 1

A, B, E

Explanation:

both angles are acute

The sum of the measures of the two angles is 75°

The measure of neither angle is more than 75°

Answer 2

Explanation:

The sum of the measures of the two angles is 75° because of the sum of angles in a triangle which means that both angles are acute. This also means that the measure of neither angle is more than 75°.
