Every point in the unit circle is identified either by its coordinates 
or by the angle it forms with the x-axis, 
.
The trigonometric functions associate with every angle and the correspondant coordinates the two values
This procedure can be done for every angle , so you don't have to work with acute angles only.
Answer:
Minimum
Step-by-step explanation:
A minimum occurs when the line goes from decreasing to increasing
It is the right answer........
The length is 32 and the width is 1. 32÷2 is 16. 16-15 is 1. 32+32+1+1 is 66
4.7 because if you plug it in- (2,1) and (6,6) it is 4.7 units
