Answer:
maybe the amount of money by each student
it approx 103.2 degree
Step-by-step explanation:
s=90+tan^-1(1÷3√2)
I add 90 base on the coordinate , taking the centre of the circle place at origin
5.5
Add 12 to both sides:
5r^2 = 80
Divide by 5:
r^2 = 16
Square root both sides:
r = +/- 4
The answer is {+/- 4}.
