Question

How can I find the value of each variable​

Answer 1

x=20

Explanation:

So, they are vertical angles so they would be EQUAL.

The equation you would use to solve for 'x' would be:

3x=80-x

Then, you would solve for x. First you would need to get all the x's on the opposite side of the numbers.

3x=80-x

Add x to both sides

4x=80

Then, you would have to divide on both sides.

4x=80

Divide by 4 on both sides

x=20

Then, if you need to find out what the angles would be, just plug x in.

3(20) = 60

80-(20) = 60

Hope this helped!! :)
