Extremely hard trigo prob: "Nathan is swimming across a river from A to B..."
Nathan is swimming across a river from A to B. He iscurrently at N, having swum 30 m. If he was to changecourse and head directly for the opposite bank, he will savehimself 20 m of swimming. Given that the river is 50 m wide,how much further must Nathan swim to get to B?
