  9. Trigonometry and Bearings Bearing is an acute angle based off the North - South line. N 38º W

  10. A nautical problem A yacht is going 14 knots East for 3 hours, then turns N 42º E for an hour. How far from port is the yacht.

  11. A nautical problem Need to find a hypotenuse of a larger triangle. To find the distance.

  12. A nautical problem The extension helps us find the hypotenuse. We have a few angles and the distance to add.
