Q 1. angle BAC will be equal to angle BDC. We know that angles made by a chord in a segment are equal. Hence angle BAC = 40 dgree

Q.2. Use the theorem: Angles by a chord in a segment are equal.

Thus angle ABC = angle ADC = 51 degree

Angle D = 79 degree As you have rightly found.

Thus angle ADB = 28 degree - Apr 12th 2013, 04:15 AMibduttRe: Work with Cirlces
Q 3 . You are on the right line. angle AOB = angle BOC = 35 degree. Thus angle AOC = 70 degree

Hence reflex angle AOC = 360 - 70 = 290 degree
