Question

From the figure find the value of 'x'.​

Answer 1

AOC = 4x

BOC = 5x

We know that AOC + BOC = 180°(Since AOC and BOC are linear pair)

= 4x + 5x = 180

= 9x = 180

= x = 180/9

x = 20

Answer 2

Answer:

20°

Step-by-step explanation:

angle AOC and angle BOC are linear pair angle

AOC+BOC=180°

4x+5x=180°

9x=180°

x=180/9

x=20°
