The diagram shows rays of light from a point source, p, that reach a detector, d, along two paths. one path is a straight line, while the other is bent by reflection off a mirror. what is the value of b, correct to one decimal place? assume that all the points in the diagram lie in the same plane.

5.4

4.2

3.6

2.8

The answer is C) B = 3.6.

Step-by-step explanation:

I took the test and got 5/5 correct on the test

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
