Answer:

1. complementary

2. neither

3. supplementary

4. complementary (x = 6)

10x + 30 = 90 x + 3 = 9 x = 6

5. supplementary (x = 20)

4x + 40 + 3x = 180 7x = 140 x = 20

6. x = 50.5

2x + 79 = 180 2x = 101 x = 50.5

Explanation:

When the measurement of the angles adds up to 90 degrees, the angles are complementary. When the sum of the angles is 180 degrees, then they are supplementary.

Answer:

supplementary angles - two angles are supplementary when they add up to 180 degrees (a straight line)

complementary angles - two angles are complementary when they add up to 90 degrees (a right angle)

hopefully this helps! :)
