Today is my birthday guess how old i am

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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°

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
