Well…geometry is somewhat fuzzy to me but heres what I got for answers:

1. B (you set it up as an equal algebra problem: 3x -1 = 2x + 13, and then solve because the definition of ‘bisects’ means split an angle equally)

2. i don’t know, sorry! 🙁

3. 128 (draw it on a peice of paper – B is a ray, D is a ray, A is the vertex and C is another ray)

4. Set it up as equal parts (75 degrees and 2x are what make your angle as a whole) that make a whole (3x for all the angles together), so the problem should look like this: 3x = 75 + 2x, and solve.

Well, hope you can at least get something out of this…:)
