Answer:
x = 4
Step-by-step explanation:
These are vertical angles. This means that the angle measurements of both are equal to each other. Set the angles equal to each other:
3x + 20 = 2x + 24
Note that you are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 2x and 20 from both sides:
3x (-2x) + 20 (-20) = 2x (-2x) + 24 (-20)
3x - 2x = 24 - 20
Simplify. Combine like terms:
3x - 2x = 24 - 20
x = 24 - 20
x = 4
x = 4 is your answer.
