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°
