Question

A boat is anchored 2.2 km due south of a lighthouse. Along the shore, the town of Beachton is 16.8 km due east of the lighthouse. what is Rounding it to the nearest tenth.

Answer 1

Pythagorean Theorem .. 2.2^2 + 16.8^2 = c^2
                                         287.08^2 = c^2
                                           16.9  =  c

This is the approximate distance from the boat to the town.
