Question

What is the value of x?

  1. 9
  2. 27
  3. 137

hintHint:

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

The correct answer is: 9


    Here, we have to find the value of x.
    From vertically opposite angles,
    5x = 45
    x = 9
    Hence, the correct option is (a).

    When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.

    Name a pair of angles that are vertical.

    They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.
