so arc length of FE would be 70 cuz 360-290=70, but ? would be 35 because its the inscribed angle of that arc length?

I mean do you want the proof for why the inscribed angle is half the arc length?

#

This is an isosceles triangle problem if you want to solve it yourself (as a hint)

let the centre be O
<GOF = 220°
<GEF = 220/2 = 110°
<GOE = 70°
<GFE = 70/2 = 35°
🔺️GEF:
? = <EGF = 180°-110°-35° = 35°
