To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.
First you have to use the formula which is r to the second times height times pi
You would do 4 times 2 equals 8 then multiply 8 times 10 equals 80 then multiply that answer times 3.14 then your answer is 251.2
Answer:
$330
Step-by-step explanation:
A simple way to do it is to see that it already has 20 on the graph. 20 is half of 40, so that stands to reason that $165 from 20 hours turns into $330 from 40 hours since it is double the work double the money.
