I'm assuming you're solving for x, in which case, the answer is -9

Step-by-step:

4x + 10 = -26

Subtract 10 from both sides

4x = -36

Divide each side by 4

x = -9

X=-9

Step-by-step explanation:

4x+10=-26

4x=-26-10

4x=-36

x=-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°
