Question

Find the value of x.​

Answer 1

So these are vertical angles (share a vertex) which means they are the same measure. Set them equal to each other to find x

`(5x) = 100`

`(5x)/(5) = (100)/(5)`

`x = (100)/(5)`

Answer:

`x = 20`

Answer 2

Answer: x = 20

Steps:
5x = 100°
x = 100/5
x = 20
