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.
15% of 40 = 6 so I’m guessing it would be 6
Because vertical angles always equal each other. linear pairs always equals 180 degrees always. hope this helps :)
