-14.5
Basically, -(7.5+4) is -11.5 and then combine -3 with -11.5 which yields -14.5
I don't really like these algebra problems which pretend to be geometry.
The bisector makes two equal angles, so
x/2 + 17 = x - 33
50 = (1/2) x
x = 100
That means ABC = 100/2 + 17 = 67 degrees
CBD = 100 - 33 = 67 degrees, equal so that checks
We're asked for ABC which is 67 + 67 = 134 degrees
Answer: 134°
Nothing more can be done to this problem, it stays the same.
