Answer: 4.5

Step-by-step explains:  1) 2r - 9 = -18

                                          2r - 9 + 9 = -18 + 9

                     2)  ( 9 + 9 )      Add the numbers

                       ( -18 + 9 )    add the numbers

                                            2r = -9

3) Divide both sides of the equation by the same term

4) Cancel terms that are in both the numerator and denominator

                                            r = 9/2 = 4.5

Hunter is bisecting the angle shown. When drawing the arcs centered on points P and Q, why must he keep the compass the same wid
S_A_V [24]

Answer:

The arcs are drawn to find a point on the bisecting ray. If the arcs are the same width, it makes sure that they are equidistant from the points on the rays of the angle. This causes the point to be on the bisecting ray.

Step-by-step explanation:

Bisection of an angle implies dividing the angle into two equal parts. The ray that divides the angle is called a bisector.

The hunter should use the same radius or width to draw the two arcs, using points P and Q as the center interchangeably, so that they would intersect at an equidistant point to P and Q. The point of intersection lies on the bisecting ray of the angle.
