WebWhat is the measure of ∠BOA and ∠AOE in the circle shown below? Solution Since BE is a straight line (diameter of the circle) then, ∠BOA + AOE = 180° (x + 50) ° + (x + 10) ° = 180° 2x + 60°= 180° Subtract 60° on both sides. 2x = 120° By dividing both side by 2, we get x = 60° Now substitute. (x + 50) ° = 60° + 50° = 110° (x + 10) ° = 60° + 10°
