Answer:
x=2
Explanation:
Sense this is an isosceles trapezoid (side lengths are congruent) opposite angles (85 and 44x+7) are supplementary (add up to 180 degrees).
85+44x+7=180
Combine like terms.
44x+92=180
Do inverse operations (First, Subtract 92 from each side of the equation.)
44x=88
Then, divide 44 from both sides to solve for x.
x=2
