Match the following definitions. 1. Angles with sides that form two pairs of opposite rays
2. Angles with measures that add to 180°
3. Angles with measures that add to 90°
4. Angles in the same plane with a common vertex and a common side but no common interior points.

A: supplementary angles
B: vertical angles
C: complementary angles
D:adjacent angles

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
