Figure pqrs is a parallelogram. what are the measures of angles p and s? ∠p = 20°;   ∠s = 160° ∠p = 40°;   ∠s = 140° ∠p = 140°; ∠s = 40° ∠p = 160°;   ∠s = 20°

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°
