Answer:

1. complementary

2. neither

3. supplementary

4. complementary (x = 6)

<em>10x + 30 = 90         x + 3 = 9          x = 6</em>

5. supplementary (x = 20)

<em>4x + 40 + 3x = 180       7x = 140       x = 20</em>

6. x = 50.5

<em>2x + 79 = 180     2x = 101       x = 50.5</em>

Step-by-step 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! :)
