Question

Help me find the X please !! Thank youu

Answer 1

We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:

`7x-99=2x+1`

`5x-99=1`

`5x=100`

`x = (100)/(5) = 20`

So, your answer is 20°.
