Solve for x in the equation x^2+20x+ 100–36 O x--16 or x=-4
Ox=-10
Ox=-8
Ox=4 or x= 16

answer: answer

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°

answer:   c ?
