Question

In the given figer,o is the centre of circle and <OAB =50°. then , <BOD=

b.50°
c.100°
d.80°​

Answer 1

Answer:

c, 100

Step-by-step explanation:

in the triangle AOB

OA = OB (radius)

so it's a isosceles triangle

so angle ABO= 50

so angle AOB = 180-50-50= 180-100= 80

and angle BOD is the linear pair of AOB

so angle AOB +angle BOD =180

80+angle BOD =180

angle BOD =180-80=100
