Question

Can Someone please help me with this math problem.

Answer 1

`\huge\boxed{x=9}`

Explanation:

We know that ∠A and ∠B are the same exact length. Since one of the angles is given to us in an exact length, we can set the measures equal to each other.

`4x + 9 = 45`

Let’s solve for x.

`4x +9-9=45-9\\\\4x=36\\\\x=9`

Hope this helped!
