Answer:

  3.88 nm

Step-by-step explanation:

The angle at Port Latta between the actual direction of travel and the destination at Lookout Point is 90° -75° = 15°. The sine function relates the angle, the side opposite, and the hypotenuse of a right triangle, so you have ...

  sin(15°) = (distance to Lookout Point)/(15 nm)

Solving for the desired distance, we have ...

  distance to Lookout Point = (15 nm)sin(15°) = 3.88 nm

The yacht is 3.88 nautical miles from Lookout Point.

In a short answer, to find average you need to add it all up and divide by the number of things you added. Ex. say I want to find the average for my english class, my grades are 90, 98, 100, 87, and 70.
