Question

find the value of
of x in given figure
​

Answer 1

To Find:

The value of x.

Solution:

The Vertically opposite angle of x is x because vertically opposite angles are equal.

3x + 10° + x + 90° = 180° ( Sum of all the angles lying on a straight line is 180° )

or, 4x = 180° - 100°

or, x = 80° / 4

or, x = 20°

Answer:

The value of x is 20°.
