The sum of all the angles made by a straight line is 180°. Then the value of x is 61°.
<h3>What is an angle?</h3>Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The angles are shown on the diagram.
The angles are 52° and 67°. And let the other angle be x.
We know that the sum of all the angles made by a straight line is 180°.
Then we have
x + 52° + 67° = 180°
On simplifying, we have the value of x.
x = 61°
Thus, the value of x is 61°.
