Answer:
50 degrees.
Step-by-step explanation:
Angle FGE =
because angles on a straight line add up to 180 degrees.
Angle EFG =
(Angles in a triangle add up to 180)



Add 20 to both sides:


Subtract 6x from both sides:


Angle 
It's not specific enough to solve...so far it would only be f(3)
Check the picture below.
we know that AL is an angle bisector, so the angle at A gets cuts into two equal halves, we also know the angle at B is 30°, so the triangle ABC is really a 30-60-90 triangle, meaning the angle at A is really a 60° angle, cut in two halves gives us 30° and 30° as you see in the picture.
if the angles at A and B, inside the triangle ABL, are equal, twin angles are only made in an isosceles by twin sides, that means that AL = BL.
Looking at the triangle ALC, we can see is also another 30-60-90 triangle, and we can just use the 30-60-90 rule to get x=CL.
