x+12
The general form of such an equation is
x^2 + y^2 = r^2 where r = radius
In this case r^2 = 4^2 + 5^2 = 41
So the required equation is x^2 ^ y^2 = 41

Answer: 110 degrees</h3>
======================================================
Work Shown:
x = measure of minor arc CL
angle J = ( (far arc) - (near arc) )/2
angle J = ((red arc) - (yellow arc))/2
angle J = ( (minor arc CL) - (minor arc CK) )/2
35 = ( x - 40 )/2
35*2 = x-40
70 = x-40
x-40 = 70
x = 70+40
x = 110
Minor arc CL = 110 degrees
Average speed: distance traveled/elapsed time
= 75/30
= 2.5 meters per second.
Best of Luck!
