hi guys can you please help me with this problem:
A street light is mounted at the top of a 15ft-tall pole. A man 6ft tall walks away from the pole with a speed of 5ft/s along a straight path. How fast is the tip of his shadow moving when he is 40ft from the pole?
is this picture I made the right idea?
I don't quite see the relevance of the 6ft since the line reaches from the top anyway. I believe I use tan =opposite/adjacent
