Someone help, so far I found out that AGE and FHD are Alternate Exterior Angles, i think. I can’t seem to figure out what to do next to find the answer. Someone please help with steps. Thank you!

Answer:
AGE=150
Step-by-step explanation:
FHD and GHC are supplementary, so:
180-30=150
CHG is corresponding to AGE, so AGE=150
