If one line intersects the other, they together form four angles. They are called in my math study verticals and neighbour angles. Two vertical angles are equal and the sum of two other neighbour angles is 180°. I guess, there is no need to draw a picture. An angle ABC and an angle DBE are verticals thus they are equal.
(X-2)(2x+2)=(x-1)(x+4)
2x*x-4x+2x-4=x*x-x+4x-4
x*x-5x=0
x=5°. So

(x-2)(2x+2) = (x-1)(x+4) (vertically opposite angles)
2x^2+2x-4x-4 = x^2+4x-x-4
x^2 -5x=0
x(x-5)=0
x= 0 or x=5
x not = 0
x=5
Plug value of x
(x-1)(x+4)
angle =36
angle CBE = 180-36 =144 ( supplementary angle)
