If trap is an isosceles trapezoid what is the value of x

The value of X is 22.

In the case of an isosceles trapezoid if there is any lower base angle is supplementary to any upper base angle.

So,  

6x + 2x + 4 = 180

8x + 4 = 180

8x = 176

x = 22

Therefore we can conclude that The value of X is 22.

Step-by-step explanation:

In an isosceles trapezoid any lower base angle is supplementary to any upper base angle, thus

6x + 2x + 4 = 180, that is

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22 → B
