Question

if o is the centre of a circle as shown in figure find CBD

Answer 1

The answer is CBD=55

Answer 2

Answer:

125°

Step-by-step explanation:

Major arc AC subtends reflex angle at the centre.

So, angle ABC = 1/2 x 360 - 110.

                        = 1/2 x 250

                        = 125 degree ( angle subtended by an arc at the center is double the arc subtended by it on any other point on the circle.)
