Question

If o is the center of the circle find angle adb if angle aob is 100

Answer 1

Given that O is the centre of the circle and angle AOB = 100°


AB is the chord which is common in Angle AOB and angle ADB. We know that :-

'The angle subtended by a chord is the double of the angle subtended by the chord at any point on circumference'

So,

angle AOB = 2 × angle ADB

=> 100 = 2 × angle ADB

=> angle ADB = 100/2

=> angle ADB = 50°


Answer :- 50°
