Aboat sails 20 miles wast of the port and then 15 miles south to an island how far is the boat from the port if you measure thr distance in a straight line ?

25 miles

Step-by-step explanation:

Given: A boat sail 20 miles west of the port and then 15 miles south to an island.

Picture attached.

The distance from port to island could be measured in a straight line. It will form a hypotenous.

∴ we can use Pythogorean theorem to find the distance.

Where, "a" is adjacent= 20 miles and "b" is opposite= 15 miles.
