Identify the polygon and classify it as regular or irregular A. quadrilateral; regular
B. quadrilateral; irregular
C. pentagon; regular
D. pentagon;irregular

B. quadrilateral; irregular

Step-by-step explanation:

Quadrilateral because it has 4 sides

Irregular because its angles and sides aren't all equal

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°
