The value of angle x will be equal to 20°.
What is a supplementary angle?
If two angles sum up to 180 degrees, they are referred to as supplementary angles. A straight angle is created by supplementary angles (180 degrees)
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that the three angles are x, 3x, and 100 degrees. The value of the angle x will be calculated as below:-
For supplementary angles, the sum of the angles is 180 degrees.
x° + 100° + 3x° = 180°
4x°+100°=180°
4x=180°-100°=80°
x=80° : 4
x=20°
Therefore, the value of angle x will be equal to 20°.
