Answer 2

Answer:

x = 10.

Step-by-step explanation:

We have to find value of x

Exterior angle of B is given 80.

Let angle B of parallelogram be y

y + 80 = 180     ( Linear pair. )

y = 180 - 80

y = 100

Now angle D of parallelogram will be 100.

Because opposite angles are equal.

3 x + 50 + 100 = 180    (  Linear pair. )

3 x + 150 = 180

3 x = 180 - 150

3 x = 30

x = 10

Thus we get x = 10.
