Figure ABCD is a trapezoid. Find

the value of x.
2x
B.
С
15
3x + 10
ya
D
x = [?]

Answer 1

x = 4

Explanation:

The mid segment is half the sum of the parallel bases, that is

`(1)/(2)` (2x + 3x + 10) = 15 ( multiply both sides by 2 )

5x + 10 = 30 ( subtract 10 from both sides )

5x = 20 ( divide both sides by 5 )

x = 4
