A ship sailed from Port K to Port L. Port L is located 28km East and 16km South of Port K.
Calculate the distance of KL and the bearing of Port L from Port K.
Give answer correct to 3 significant figures.

This requires only the Pythagorean Theorem:



where X and Y are the two sides of the right triangle and R is the side opposite the 90 degree angle.

Also, the bearing can easily be calculated from the two given distances.

Per the diagram:



Do you want a bearing or an azimuth? There is a difference.

An azimuth is an angle turned clockwise off due north. For that, just add the answer from above to 90 degrees.

A bearing is done in quadrants, as in land deeds.

Your bearing would be

The bearing from Port K to L can be calculated from arctan(16/28) - this is the angle south of east, so add 90 degres to get a bearing from north.

Pythagorean Theorem...

The hypotenuse is equivalent to the square root of the sum of the square of both sides.
