Question

A sailboat leaves port and sails 12 kilometers west and then 9 kilometers north. The sailboat is now kilometers from port

Answer 1

15

Explanation:

Answer 2

Use the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2, often written
`a^2+b^2=c^2` where a and b are the lengths of the legs of a right triangle, and c is the length of the hypotenuse.

In this problem, a = 9 and b = 12.


`c^2=9^2+12^2=81+144=225 \\ c=√(225)=15`
