14. if m< 2 = 12k +15 and m< 26 = 35+2k, what is
the measure of < 2

a.39
b. 2
c.123
d. 9

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°

d is the only accurate one
