What have you attempted with any of these three problems?

Your first question says "An isosceles trapezoid has legs AB, AC, and base BC". That makes no sense. Where the fourth vertex? And what do you mean by the "legs" of a trapezoid? If you mean the non parallel side, they can't both pass through A.

Your second question has what appears to be a parallelogram with vertices A, B, C, and D and then you say "A= 3y- 1", "B= 2x+ 24", "C= 2y+ 40", and "D= x+ y". What are those? If A, B, C, and D are points, they cannot be equal to numbers.

Finally, your third question says "A trapezoid has base length of (7x+ 2) units and 11 units. Do you mean "base lengths"? that is, that the two bases have length 7x+ 2 units and 11 units? You also say "its midsegment has a value of 5x- 3". What do you mean by "midsegment"? Do you mean that the segment parallel to both bases, half way between the bases, has length 5x- 3 units? But there is [b]no[/b[ question asked about this trapezoid!
