Given EF is the midsegment of Isosceles trapezoid ABCD. BC = 17x, EF = 22.5x + 9, and AD = 30x + 12, find AD.

AD should be 30x. it's already given. if you want to find x the solution will be :The midsegment (or median) in an isosocles trapezoid is half the sum of the lengths.
2(22.5x+9)=17x+30x+12
45x+18=47x+12
18-12=47x-45x
6=2x
*x=3

Weegy: Surface area of prism = (S1 + S2 + S3 + S4 +... Sn) x length = perimeter x length
Where S1, S2, S2, ... = length of the sides of the base
Therefore perimeter = Surface area/length = 175/5
Perimeter of base = 35 feet <<< (More)
