Homework Statement
A man is going to sail his sailboat across a bay to a harbor from his dock and wants to know how long it will take him. He knows that if he sails directly across the bay from his dock he will reach the harbor. However, he has no charts so he doesn't know the distance to the harbor. There is a tower at right angles the line between the dock and the harbor. The tower is 3.75x10^3 meters from the dock and is 10^2 meters high. He gets into his car and drives to the tower. He climbs 50 meters up the tower until he can see the harbor. He measures the angle between his line of sight to the harbor and the direction of the dock to be 79.64 degrees. He estimates that his boat can maintain a velocity in the direction of the bow of 100 meters per minute with the wind that is blowing. How long will it take him in hours and minutes to sail across the bay to the harbor.Homework Equations

The Attempt at a Solution
I've attempted to draw the picture, but I know my drawings are incorrect because my answers come out to be negative somehow. If someone could just draw the picture for me, I could go on from there
