Question

*WILL MEDAL* In order to keep a boat from drifting away, the boat is tied to a pier with a 60-foot rope. When the boat drifts as far from the pier as the rope will allow, the rope forms a 15° angle relative to the horizontal water line.
To the nearest foot, find the maximum horizontal distance, d, that the tied-up boat can drift from the pier. *Can you show me how to work it out?*

Answer 1

Answer 2

Adjacent

Answer 3
