Question

Please hurry solve for c in the diagram in the picture!

Answer 1

40

Explanation:

The angles are vertical angles so they equal each other.

So 3x=120 divide each side by 3 to get x by itself

So x is 40

Answer 2

3x and 120 are both vertical degrees.

Essentially, vertical degrees are two angles that are on the exact opposite sides. These vertical degrees are always congruent.

Since 3x and 120 are congruent, we can make an equation to solve for x:

3x = 120
Divide:
x = 40
