Question

in the give figure if AOB is a straight line then angle BOC is ​

Answer 1

Answer:

80...................

Answer 2

Step-by-step explanation:

2x +30 + 2x + 10 = 180 ( Angle on a straight line)

4x + 40 = 180

4x = 180 - 40

4x =140

X = 3.5

Angle Boc = 2 (3.5) + 10

17 degree

Angle C00= 2x +30

2(3.5)+30

=37
