Answer:
45°
Step-by-step explanation:
AOC=AOB+BOC
=60°+30°
=90°
We know that angle subtended by an arc at the centre is double the angle subtended by it any point on the remaining part of the circle
ADC=1÷2AOC=1÷2×90°=45°
Hope u have understand

Answer:
ADC = 45
Step-by-step explanation:
∵ AOC is a central angle
∵ ADC is an inscribed angle
∵ AOC and ADC are subtended by the same arc
∴ AOC = 2 ADC
∵AOC = 60+30 = 90°
∴2ADC = 90°
∴ ADC =45°
