Members of an art club paint a mural on a large wall that is shaped like a trapezoid. One base of the trapezoid is 20 feet long and the other base is half that length. A gallon of the paint they use covers 300 square feet. They use all but 1/5
of one gallon of the paint. What is the height of the wall? Complete the explanation.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
