Ncircle d, angle adc measures (7x + 2)°. arc ac measures (8x - 8)°. what is the measure of ? 36° 43° 72° 144°

the answer is b

what is the graph

step-by-step explanation:

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°
