A ship sails east for s miles and then south for 4 miles How

A ship sails east for s miles and then south for 4 miles. How far is the ship from its starting point? Enter the exact answer. The ship is miles from the starting point.

Solution

Here we get a right triangle with a=5 and b=4

so we get c=sqrt(a²+b²)

c=sqrt(25+16)=sqrt41

Therefore the ship is sqrt 41miles from the starting point
