You can put this solution on YOUR website! a barge is pulled by two tugboats.the first tugboat is travelling at a speed of 15 knots with heading 130 degrees , and the second tugboat is travelling at a speed of 16 knots heading 190 degrees . find the resulting speed and direction of the barge.
-----------
x-coordinate:: 15cos(130)+16cos(190) = -25.4
y-coordinate:: 15sin(130)+16sin(190) = 8.71
-------
Direction:: arctan(-25.4/8.71) = -71.07 degrees
-------
Speed:: sqrt[25.4^2+8.71^2) = 26.85 mph
