Question

I really don't understand on how to solve this

Answer 1

Hey there! :D

These are vertical angles. They have the same measure, so they are equal to each other.


`6x+25= 2x+105`

Subtract 25 on both sides.


`6x=2x+80`

Subtract 2x on both sides.


`4x=80`

Divide both sides by 4.


`x=20`

I hope this helps, and have a nice day!
