Mark was thinking of a number. Mark subtracts 6.2 from the number and gets an answer of 68. Form an equation with x
from the information.

X= 6.2 + 68 ???

Step-by-step explanation:

I'm not sure that's what I would write in an exam

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: the answer is e
