Question

d) મોચીને ક્યારે દુ:ખ થયું?​

Answer 1

Answer:

It is given that,

AOC = AOB+BOC

So, AOC = 60°+30°

∴ AOC = 90°

It is known that an angle which is subtended by an arc at the centre of the circle is double the angle subtended by that arc at any point on the remaining part of the circle.

So,

ADC = (½)AOC

= (½)× 90° = 45°
