Answer: x
Step-by-step explanation: So you have 103 degrees and you know that E->F and H->G are the same degree. H->F divides the circle in half. Half of a circle is 180, so 180-103 is 77.
H->G and E->F are 77 degrees. Since E->F is 77 degrees, add D->H to 77, which gives you 92, then subtract 92 from 180. That will give you the degree of D->E.
D->E is 88 degrees. Thus, 18x-2=88. 18x=90. x=5
