The rescuer and the evacuee lie on the opposite banks of a river. Rescuer A is on bank A while the evacuee is on bank B. Rescuer C is in point C which is 250 meters away from Rescuer A (see figure). Given that ∠A and ∠C are 64° and 44° respectively as shown in the figure, who can rescue the evacuee with the least amount of resources? Explain your answer.
