Best ResponseYou've already chosen the best response.0From the figure, it seems that the parallel sides are AB and CD. You wrote the parallel sides are AD and CD?

Best ResponseYou've already chosen the best response.0and to be able to solve for w, you may have been given a perimeter..?

Best ResponseYou've already chosen the best response.0An isosceles trapezoid has congruent legs (the nonparallel sides).

Best ResponseYou've already chosen the best response.0unless you use the idea that AD = BC so 3w  5 = 2w + 7

Best ResponseYou've already chosen the best response.0We don't know anything about the lengths of sides AB and CD. We only know they are parallel. We do know sides AD and BC are congruent, so we can set their expressions equal and solve for w.

Best ResponseYou've already chosen the best response.03w  5 = 2w + 7 Can you solve for w?

Best ResponseYou've already chosen the best response.0Start by subtracting 2w from both sides. Then add 5 to both sides. What do you get for w?

Best ResponseYou've already chosen the best response.0No. First, subtract 2w from both sides: 3w  5 = 2w + 7 w  5 = 7 Now add 5 to both sides: w = 12
