52 is 65% of what?

45% of 40 is what number?

Let, that number = x

It would be: x * 0.65 = 52

x = 52 / 0.65

x = 80

So, that number and your answer is 80

18 is 45% of 40

45%/100 = 0.45

0.45*40=18

4y - 6 + y^2 - 9 = y^2 + 4y - 15

step-by-step explanation:

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
