Using the Exterior Angle Theorem, solve for x.

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

won't that be plagrisim thought?

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°

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
