Question

Can i get a good answer as to how to solve this

Answer 1

This is a trick question. DFG is the isosceles right triangle so DGF=FDG=45 degrees. We have triangle DEF congruent to DGF, side-side-side. So EDG=90 degrees, so ADG=90 (they're supplementary). That's the measure of the arc AG.

Answer: 90 degrees
