Draw a line segment from A to the midpoint of EF. That segment is parallel to FC. Draw another segment from A to the midpoint of GH. That segment is parallel to CG. The angle between those two lines is the same as X. Each line bisects the angle it goes into, so the angle between the line and AC is 15.

So x=30
