Question

in the given fig ,AOB is a line , find x ​

Answer 1

Given:

1. angle COD = 90°
2. AOB is a line

To find:

• The value of x.

A linear pair of angles must add up to 180°.

Solution:

3x + 90° + x = 180°

or, 4x = 180° - 90°

or, 4x = 90°

or, x = 90/4

or, x = 22.5

Answer:

The value of x is 22.5°

3x = 3(22.5) = 67.5°

x = 22.5°
