Question 7: Find the value of x. The numbers below are in degrees.<br> 140<br> S<br> 50<br> 20
Lyrx [107]

Given:

A figure.

To find:

The value of x.

Solution:

Draw two parallel lines as shown in the below figure.

If a transversal line intersect two parallel lines, then alternate interior angles are same.

a=20              (Alternate interior angle)

d=b              (Alternate interior angle)           ...(i)

The value of angle d is

d=50-a

d=50-20

d=30

Using (i), we get

b=30

If a transversal line intersect two parallel lines, then same sides interior angles are supplementary angles.

c+140=180

c=180-140

c=40

Now,

x=b+c

x=30+40

x=70

Therefore, the value of x is 70.
