C 10
Explanation:
The sum of the angles in a triangle is always 180 degrees. Therefore, we can set up the equation:
2x + (100+4x) + 20 = 180
Simplifying, we get:
6x + 120 = 180
6x = 60
x = 10
So, the value of x is 10.
The angle measure of a triangle are shown in the diagram.
the top of the triangle shows 2x and the bottom left shows (100+4x) and the bottom right shows 20
What is the value of x?
