Question

Can someone explain this to me?

Answer 1

Answer:

x=2

Step-by-step 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
