Already I've set up an equation for the perimeter: 2x + y = 36, where x is the radii and y is the arc length
The problem is that I don't know how to go from here...I just know that I need to possibly make a system of equations????
Recall the relationship between arc length and angle subtended by the arc..
l = theta*r????
Exactly!!
