Question

In the given figure, AOB is a line, then x​

Answer 1

Answer:

20 =x

the angle is 80°

Step-by-step explanation:

60 + 4x + 40 = 180

as it is a straight line

100 + 4x = 180

4x =80

Answer 2

The solution is here:

By linear pair Property

_________________________________________Step -1

Angle BOD =40°

Angle AOC =60°

So,

=> x+x+x = 180°

=> 40°+60°+x =180°

=> 100°+x = 180°

=> x = 180° - 100°

=> x = 80°

So your answer is 80°
