Question

In the figure, 'O' is the centre of the circle.
angle AOB = 100 find angleADB.
​

Answer 1

Answer:

100 degree

Step-by-step explanation:

Answer 2

Answer:

Angle AOB = 100°

basically Angle O =100°

So Angle D = 100° with the property of verticals opposite angles

Angle D+Angle B = 180°

D given =100°

B = D - 180°

So,B=180°-100°

B =80°

Angle A = 80° Vertically opposite angle of Angle B .

so,

Angle A=80°

AngleB= 80°

Angle D =100°
