Which expression does not represent a square root of a perfect integer a. square root of 100b. square root of 64c. square root of 81d. square root of 89

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°

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
