Triangle V P M. Angle V is 52 degrees, angle P is 78 degrees, angle M is x degrees.
Which equation would help find the measure of ∠M?
x + 52 + 78 = 180
52 + x = 180 + 78
180 + 52 = 78 + x
180 + x = 78 + 52

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.

I'm confused on this could anyone me and show me what i need to do to solve it.
