How can i find the value of each variable

x=20

Step-by-step 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!! :)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
