4. A pathway running tangentially to a perfectly circular lagoon is to have a branching at a point 500m before the tangent point and the branching, crossing the lagoon at an initial deflection angle of 75° to connect directly to a point on the lagoon's periphery by means of a hanging bridge. If the lagoon has a diameter of 1700m, determine the following: a) the length of the hanging bridge; b) if the hanging bridge divides the area of the lagoon into two segments, compute the area of the biggest segment in km2.
