All possible ways of arranging the A E I O U taken two at a time

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

any options?

step-by-step explanation:

3 is greater then both of those numbers

47 - 90 = 43

43 - 180 = x

x = 137
