x + x-5 + x +23 = 180
combine like terms:
3x +18 = 180
subtract 18 from each side:
3x = 162
divide both sides by 3
x = 162 / 3 = 54
Angle x = 54 degrees
Angle x-5 = 54-5 = 49 degrees
Angle x +23 = 54 +23 = 77 degrees
27a² + 18ax + 45a = 9a(3a + 2x + 5)

This missing part is 3a + 2x + 5.

I'm guessing this is what the question is asking?
