-3

First, plug in the values of the variables. You get:
(-1) (-(2) + (5))

This simplifies into -1 (-2 + 5)

Following order of operations (PEMDAS), you do what is in the parenthesis first. -2 + 5 = 3. This leaves you with:

-1(3)

When something is directly outside of parenthesis, that means you multiply that by whatever is inside the parenthesis. -1 x 3 = -3 so -3 is your answer.

I need help solving this problem with proofs if at all possible
k0ka [10]

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°
