Since OC=8 and OC=OF, then OF=8

OEF is a right triangle, so we can find EF using


OF^2+EF^2=OE^2 \implies OF = √(OE^2-EF^2)=√(100-64)=6

Now, observe that triangles OEF and OFG are congruent: they are both right triangles, OF is common, and OE=OG because they're both radii.

So, we have


EG=EF+FG=2EF=2\cdot 6 = 12
