In a circle, the measure of an inscribed angle is half the measure of the intercepted arc.
∠BCD = arc BAD/2 ⇒ arc BAD = 2*∠BCD = 2*100 = 200°
arc BCD = 360° - arc BAD = 360° - 200° = 160°
∠d = arc BCD/2 = 160/2 =
80°
<span>2(x+4)=30
divide both sides by 2
x + 4 = 15
subtract 4 to both sides
x = 11</span>
