Answer 2

Given:

An angle=40°

To find:

The value of x

Solution:

The required measure of x is 140°.

We can obtain the required angle by subtracting the given angle from 180°.

Since the lines are straight, we know that 40° and angle x form a linear pair and are supplementary.

So, 40°+angle x=180°.

On solving, we get

Angle x=180°-40°

Angle x=140°

Therefore, the required measure of x is 140°.
