The Bermuda Triangle is an unmarked area in the Atlantic Ocean where there have been reports of unexplained disappearances of boats and planes and problems with radio communications. The triangle is an isosceles triangle with vertices at Miami, Florida, San Juan, Puerto Rico, and at the island of Bermuda. Miami is approximately 1660 km from both Bermuda and San Juan. If the angle formed by the sides of the triangle connecting Miami to Bermuda and Miami to San Juan is 55.5°, determine the distance from Bermuda to San Juan. Express your answer to the nearest kilometre.
I get 1490 km
