Would it be 150?

OpenStudy (alexwee123):

no^ 150 accounts only for the FI portion of arc FGI. You need to add 150 to the measure of arc FG to get the answer hint* A circle has a total measure of 360 and FGI is half a circle...

180

OpenStudy (alexwee123):

OpenStudy (nikato):

@alexwee123 FGI is not a semicircle FGH is. FGI is FGH +HI And HI=ED=30 So FGI=180+30
