The value of x from the diagram is 18degrees

An angle is a line where two or more lines meet.

The magnitude of two lines is known to be parallel if they have the same magnitude.

From the diagram shown, we can see that line BC is parallel to line ED

This shows that the following are true:

  • <C = <D
  • 8x and 2x are supplementary

If the two angles are supplementary, then:

8x + 2x  = 180

10x = 180

x = 180/10

x = 18 degrees

Hence the value of x is 18degrees
