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).
<u>85</u>+44x+<u>7</u>=180
<em>Combine like terms.</em>
44x<u>+92</u>=180
<em>Do inverse operations (First, Subtract 92 from each side of the equation.)</em>
<u>44</u>x=88
<em>Then, divide 44 from both sides to solve for x.</em>
x=2
