There's an island off the coast of Nova Scotia is said to have incredible treasure buried deep underground, and people have been searching for it for over 2 centuries. Based off an old map, 2 brothers started at a
reference point R and located an old tunnel 100 m North of R at point T. They then restart at point R and
turn 50° East of North (or N 50°E) and discover a shaft 84 m away at point S. What's the distance between
the tunnel and the shaft? Include a fully labelled diagram.
