What is the measure of BC
Solution:
As per Inscribed Angle Theorem: If an angle is inscribed in a circle, then the measure of the intercepted arc is twice the value of the measure of the inscribed angle.
So, as we can see in the diagram the angle inscribed in the circle is 65°.
So, the measure of intercepted arc BC is twice ∠BDC
Or, BC=2*65°
BC=130° Answer
