Question

Find the value of x in the following
figure

​

Answer 1

Answer:

The value of x is 20 degree.

Step-by-step explanation:

AB ll CD and EF is transversal.

so, angle EMD is equal to angle CMN (Vertical opposite angles)

and, angle CMN is equal to angle MNB (Alternate Interior angles)

angle MNB is equal to 5x and angle MNA is equal to 4x.

4x + 5x = 180 degree (Linear pair)

9x = 180 degree

x = 20 degree
