2) Find the measure of angle b.
Also how do I show the work for it

B=43

Step-by-step explanation:

The reason 43 is our answer here is because it is opposite of the 43 degree angle.

43 degrees

Step-by-step explanation:

You can't necessarily show work for it, you could just say that "b" is a vertical angle. A vertical angle is an angle that is congruent to the opposite angle of it on two intersecting lines. Therefore, "b" would be 43 degrees.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
