Given: A 60° angle.
Note: An angle bisector splits the angle evenly into two angles with same measurement.
First, divide the given angle into two congruent angles
60/2 = 30
Next, divide each of the angles found again into two congruent angles
30/2 = 15
You have gotten a 15 degree angle.
hope this helps
60° is 4x 15° because:

I would first divide by 2:

Then divide by 2 again:

That leaves you with a 15° angle.

Therefore, the answer is

3 pairs cost $165
165/3 = 55
1 pair cost $55
Eleven pairs would cost 11(55) = $605
The answer is 0.0009 because when you have a 5 behind the number you are trying to round, you round up
12.57 / 3 = 4.19 * 7= 29.33
