Question

In the figure, find the value of x.​

Answer 1

Answer:

20°

Step-by-step explanation:

2x + 3x +4x = 180° [straight angle]

9x = 180°

x = 180/9

x = 20°

Answer 2

Answer:

The value of x = 20°

Step-by-step explanation:

Angle AOC + angle COD + angle DOB = 180°

means, 2x + 3x + 4x = 180°

9x = 180°

x = 180°/9 = 20°

So , x = 20°

Therefore, angle AOC = 2x = 2×20 = 40°

angle COD = 3x = 3×20 = 60°

angle DOB = 4x = 4×20 = 80°
