Step-by-step explanation:
arccos(0) = 90 degrees
Cos is 0 when ever sin(x) =-1 this occurs at 270 degrees and when sin(x) = 1 at 90 degrees. However, the domain of arccos(x) is restricted from 0 to pi. So the value of arccos(0) is pi/2 or 90 degrees.
The number is 'n'.
Five times the number is 5n .
Nine more than that is 5n + 9 .
