Answer: 37 degrees
=====================================
Step-by-step explanation:
Refer to the diagram below. I've marked angles FBD and ECG in red. We can see that they are alternate exterior angles because they are
Outside (aka exterior) of the parallel lines
On alternating sides of the transversal cut
Because JD is parallel to EK, this means the alternate exterior angles are congruent. Therefore, angle ECG is also 37 degrees.
Ignore angle ABG and ignore line AH. In my opinion, this is filler added as a distraction.
