Question

10. In the given figure, AOB is a straight line.
Find the value of x.​

Answer 1

Answer:

x = 60 degree

Step-by-step explanation:

x +x+10+x+10= 180 degree. (AOB ) is a straight line

3x + 20= 180

3x = 180- 20

3x = 160

x = 160 divided by 4

x = 40 degrees

Answer 2

Answer:

x=40

Step-by-step explanation:

( x + 10 ) + ( 2x + 10 ) + x = 180°

x + 10 + 2x + 10 + x = 180°

4x + 20 = 180°

4x = 180 - 20

4x = 160°

x = 160/4

x = 40
