Question

Please help me. Solve for x in the diagram below:

Answer 1

Answer:

x = 40

Step-by-step explanation:

The angles are vertical angles.  We know that vertical angles are equal

120 = 3x

Divide each side by 3

120/3 = 3x/3

40 =x

Answer 2

Answer:

40

Step-by-step explanation:

I forgot what you would call this, but basically 3x = 120. both of the angles are the same. So divide both sides of the equation by 3. 3x/3 = 120/3 and your answer is 40.

It's a bad explanation but I hope it helps!
