Please help me! Find the value of x in each case:

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
