First, lets note that

. This leads us with the following problem:

Lets add sin on both sides, and we get:

Now if we divide with sin on both sides we get:

Now we can remember how cot is defined, it is (cos/sin). So we have:

Now take the inverse of cot and we get:

In general we have

, the reason we have to add pi times n, is because it is a function that has multiple answers, see the picture:
39/40 as a decimal is 0.975
Answer:
Step-by-step explanation:
Let x be the number of hours worked by Joshua.
Shirts ironed by Joshua in an hour = 25
Number of shirts ironed by Joshua in x hours = 25x
The number of hours worked by Luke = (x + 3)hours
Shirts ironed by Luke in an hour = 35
No. of shirts ironed by Luke in x hours = 35*(x + 3) = 35x+35*3 = 35x + 105
No. of shirts ironed by Luke and Joshua = 345
25x + 35x +105 = 345
60x = 345 - 105
60x = 240
x = 240/60
x = 4 hours
The number of hours worked by Joshua = 4 hours
The number of hours worked by Luke = 4 +3 = 7 hours
