Two arcs of the same length subtend angles of 60^@ and 75^@ at the centres of the circles.What is the ratio of the radii of the two circles?

If in two circles, arcs of the same length substend angles of 60^(@) and 75^(@) at their centres, then the ratio of their radii is-

Two arcs of two different circle are of equal lengths. If these arcs subtends angles of 45^(@) and 60^(@) at the centre of the circles. Find the ratio of the radii of the two circles.

If the arcs of the same length in two circles subtend angles of 60^(@) and 75^(@) at their respective centres, find the ratio of their radii?

If in two circle arcs of the same length subtend angle of 60^(@) and 75^(@) at the center , find the ratio of their radii.
