Which number sentence can be used to find 42 ÷ 7 = ? a. 42 x _ = 7 b. 7 x _ 42 = 42 c. 42 - 7 = _ d. 7 ÷ 42 = _

Did you write Letter choice B. Correctly?

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°

cause it equals more
