Circle section

Equilateral triangle with side 33 is inscribed circle section whose center is in one of the vertices of the triangle and the arc touches the opposite side.

Calculate:

a) the length of the arc
b) the ratio betewwn the circumference to the circle sector and the perimeter of the triangle

Correct result:

x =  29.928 cm
y =  0.302
