Please help me with math

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°

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

central angle of a triangle has the same measure as its intercepted arc.
