Question

please give me correctly answer​

Answer 1

Answer:

this is the answer 110°

Answer 2

Answer:

For this, we have to first find Angle ACB

Angle ACB

= 1/2× Angle AOB = 1/2 × 140°

= 70°

Now, reflex Angle AOB

= 360°- 140°

= 220°

Major arc AOB subtends reflex Angle AOB at the centre and Angle ADB at the remaining part of the circumference.

Angle ADB

= 1/2 (reflex Angle AOB)

= 1/2 × 220°

= 110°
