Three little birds out of my window and they told me I don’t need to worry
(a + b)2 Plug in the a and b values
(2 + 3)2 Add 2 and 3
(5)2 Multiply 5 and 2
10
When a = 2 and b = 3, (a + b)2 will equal 1.) 10.

45 or a random number lol just put in 45 and see if it orks
Um, so it's a bit awkward with this question because they actually got the x value incorrect. When they added up all the values, they got 9x - 27 = 180, but it's actually 9x + 27 = 180 because -18 + 45 is positive 27. Anyways, when you solve it correctly you get x = 17, and then you substitute it into the angles. So with 5x - 18, you are saying 5(× 17) - 18 = 67. Then with the other one you do 4(× 17) + 45 = 113. You know that x is definitely 17 because 113 + 67 = 180.
