D. 56

idk what the answer is but for the points

step-by-step explanation:

the first one and the second one that's the answer

the f

last graph i believe

step-by-step explanation:

worked it out i believe

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°
