Find all zeros of the polynomial. (Enter your answers as a comma-separated list. Enter all answers including repetitions.) P(x) = 2x3 + 11x2 + 20x + 21​

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°
