Question

Can Someone please help me with this math problem.

Answer 1

Answer:

$\huge\boxed{x=9}$

Step-by-step 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!
