Hi there!
18 is 20% of 90. Why, you may ask?
To solve we just divide both sides by 0.2
We would start off with 0.2x = 18.
NOW divide.
x = 90.
We can check this by seeing that 20% of 90 is equal to 18.
Hope this helps!
put it a little bit to the right
Ignore the fact that it says limit because when sin (pi) is here it is not an Undefined Point, whatever value the calculator says is sin(pi) is the answer.
13.69 im pretty sure because you multiply 19 by 72 and divide by 100
