Question

Find the value of x in the isosceles trapezoid if AC = 2x + 2 and DB = 4x - 6

-8

6

4

2

Answer 1

The diagonals of an isosceles trapezoid are congruent (but do not bisect each other).

AC = DB

2x + 2 = 4x - 6

Answer 2

yea i solved that and i got -4

Answer 3

I did not get -4 for x.

Answer 4

wait shouldnt it be 4

Answer 5

Yes. Would you like to work the equation?

Answer 6

2x + 2 = 4x - 6
6 + 2 = 4x - 2x
8 = 2x
4 = x

Answer 7
