what is the value of x
Thank you :)

Answer 1

B. 30

Explanation:

The given angles are vertical angles because they are opposite angles created by the same two lines. This means that their value is equal. Let's set up an equation.

85 = 3x - 5

We need to solve for x.

First, combine like terms by adding 5 to both sides.

90 = 3x

Now we want to isolate x by dividing both sides by 3.

x = 30

This is your answer.

Let's check our work by plugging x back into our equation.

85 = 3x - 5

85 = 3(30) - 5

85 = 90 - 5

85 = 85

Your answer is correct.

Hope this helps!
