Question

In the given figure, BC is the diameter of a circle and ∠BAO = 60º then What is the measure of ∠ADC ?

Answer 1

Answer:

60⁰

please select it as brailiest

Step-by-step explanation:

as angle BAO is 60⁰ so ABO is equalateral traingle and both of angle ABO and AOB is 60⁰

again, BC is a straight line

so, angle AOB+AOC=180⁰

so, AOC=120⁰

and AOC is central angle and ADC is angle of peremeter

so, ADC=½ of angle AOC

so, angle ADC=½ of 120⁰=60⁰
