Mr. Beckett can scream at a rate of 120 words per minute when he is in a good mood and he can scream at a rate of 150 words per minute when he is angry. Yesterday he was screamed 3120 words for a total of 23 minutes. For how many minutes was Mr. Beckett angry? This thing is systems of equations I need help with making the equation

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°

move it to the other side
