Q. 25.0( 1 Vote )

In Figure 5.60 POQ is straight line. The value of x is-

A. 20°

B. 25°

C. 30°

D. 35°

Answer :

Now all the three angles add up to 180° as the line PQ is a straight line and the angles form a linear pair.

40° + 4x + 3x = 180°

7x = 180 – 40

7x = 140°

x = 20°

So the correct answer is A.
