a) 136 degrees

b) 146 degrees

c) 36 degrees

d) 46 degrees

**Two angles are supplementary. One angle measures 61.5 degrees. What is the measure of the other angle?**

a) 128.5 degrees

b) 138.5 degrees

c) 38.5 degrees

d) 28.5 degrees

**What is the best definition for supplementary angles?**

a) Two or more angles whose measures add up to 180 degrees

b) Two or more angles whose measures add up to 90 degrees.

c) Two right angles.

d) An acute and an obtuse angle.

**Two angles are complementary. One angle measures (4x - 10) degrees. The other angle measures (3x - 15) degrees. Which equation should you use to solve for the measures of the angles?**

a) (4x - 10 ) + (3x - 15) = 90

a) 90 = 9x - 15

b) 90 = (4x + 1) - (5x - 16)

c) 90 = 9x + 17

d) 90 = 20x - 17

**Two angles are supplementary. One angle measures (3x + 2) degrees. The other angle measures twice that amount. What equation could be used to solve for x?**
