     1. The Bermuda Triangle is a geographical area in the Atlantic Ocean that is infamous for
     the many people, aircraft, and surface vessels said to have disappeared within its bounds.
     The corners of the Bermuda Triangle are Bermuda, Miami, and San Juan, Puerto Rico.
                                                                                         (5 pts)
     BMS has sides b = 850 miles, m = 925 miles and s = 1300 miles. Find the distance
     from San Juan to a ship that has sunk half way between Bermuda and Miami.
