    Use the Inscribed Angle Theorem |dw:1434074532155:dw| https://www.mathsisfun.com/geometry/circle-theorems.html Use the fact that $$ 2\angle A=\text{Arc(B)} $$ So, $$ 2\angle E =\text{Arc(HGF)}\\ 2\angle G =\text{Arc(HEF)}\\ $$ The two arcs sum to 360 degrees because they go around once $$ \text{Arc(HGF)}+\text{Arc(HEF)}=360 $$ Substitute and solve. This shows that E and G are supplementary You do this now for H and F

    I'm not understanding this very well. GE and HF sum up to 360 so HF sums up to 180?

    @ybarrap I kind of get it now. So what do E and F equal and why?
