not sure why they put the x bit

ok so know this:
AGE=HGB=CHG=FHD
and
AGH=EGB=CHF=GHD
and
AGE+AGH=180


11.
AGE=FHD=30

12.
AGH=CHF=150

13.
CHF=BGE=110

14.
CHG+HGA=180
CHG+120=180
CHG=60

15.
BHG=3x=AGE=CHG=FHD
not sure, but if we did use the fact that BGH+DHG=180 and BGH=3x and DHG=2x+50 then BHG=78 degrees

16.
GHD=2x+50=CHF=EGB=AGH, if we use facts above then GHD=102 degrees
