x = 30

This answer makes a lot of use of supplementary angles.  Because of it <GFE is 180 - 4x and <GEF is 180 - 2x.  Then, because there are 180 degrees in a triangle you can determine that:

180 - 2x + 180 - 4x + x = 180

360 - 6x = 180

-6x = -180

x = 30

Hope it helps <3

Answer:

x =36

Step-by-step explanation:

The inside angle on the left is 180 -2x

The inside angle on the right is 180 -4x

The sum of the angles of a triangle is 180

180 -2x + x + 180 -4x = 180

Combine like terms

360 - 5x = 180

Subtract 360

-5x = -180

Divide by 5

x =36
