You have a triangle the left height is 126 degrees and the right height is 43 degrees . work out the size of x

11 degrees

Step-by-step explanation:

The question is not clear but if you are asking for the meansure of the angles of the triangle then this is the

The total measure of degrees in a triangle is 180 degrees, and the two measures is 126 + 43 = 169.

180 - 169 = 11 degrees

hello from mrbilldoesmath!

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
