divided by 2 - 5. If there is a remainder, express the result in the form q(x) +
r(a)
b(x):

Step-by-step explanation:

5 | 1  -1  -19  -10   17

___   5  20_ 5  -25____

    1   4    1   -5  | -8

So, we show our answer as

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°
