The measure of angle x is 115 degrees

Step-by-step explanation:

Supplementary angles are angles which, when added together, equal 180 degrees. So, subtracting 65 from 180 would get you the answer(115).

angle x is 115 degrees

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°
