Question

What’s the measure of A

Answer 1

Answer:Angle A is equal to 113

Step-by-step explanation:

If two angles are vertical, that would make them equal to each other.

7x-20=6x-1

Add on to both sides

7x-19=6x

Subtract Seven from both sides

-19=-x

Divide by negative one to get rid of the negative

19=x

Then plug x into the equation 7(19)-20
