Answer:
n, h = Naomi's and Hudson's work hours, respectively
n + h = 13
35n +20h = 395
Step-by-step explanation:
We are asked for the number of work hours of Naomi and Hudson. It is convenient to define the variables n and h to represent those hours, respectively. Then the system of equations is ...
n + h = 13 . . . . . . . . . . . . total work hours
35n +20h = 395 . . . . . . total shirts ironed
_____
The solution is Naomi worked 9 hours; Hudson worked 4 hours.

Answer:
If P = (x,y) then formulas for each trigonometric functions are:
sin x = y/r
cos x = x/r
tan x = y/x
cot x = x/y
sec x = r/x
cosec x = r/y
where r = √(x²+y²).
First find r:
r = √(13²+84²)=√(169+7056)=√7225=85.
Then just substitute:
sin x = 84/85
cos x = 13/85
tan x = 84/13
cot x = 13/84
sec x = 85/13
cosec x = 85/84
