supplementary angles practice

1 answer

1. Find the measure of the complementary angle to a 45-degree angle.

Solution: The measure of the complementary angle to a 45-degree angle is 90 degrees - 45 degrees = 45 degrees.

2. Find the measure of the supplementary angle to a 120-degree angle.

Solution: The measure of the supplementary angle to a 120-degree angle is 180 degrees - 120 degrees = 60 degrees.

3. If angle A is a supplementary angle to angle B and angle A measures 60 degrees, what is the measure of angle B?

Solution: The measure of angle B is 180 degrees - 60 degrees = 120 degrees.

4. If angle X is a complementary angle to angle Y and angle X measures 30 degrees, what is the measure of angle Y?

Solution: The measure of angle Y is 90 degrees - 30 degrees = 60 degrees.

5. Find the measure of the supplementary angle to a 150-degree angle.

Solution: The measure of the supplementary angle to a 150-degree angle is 180 degrees - 150 degrees = 30 degrees.
