Emergency Landing. A plane leaves the airport in Galisto and flies a distance 155 km at an angle 68.0 Degrees east of north and then changes direction to fly a distance 270 km at an angle 48.0 degrees south of east, after which it makes an immediate emergency landing in a pasture.
1.) When the airport sends out a rescue crew, how far should this crew fly to go directly to this plane? <--- know how to do this already and got the answer
2.) In which direction? (Express your answer as an angle measured south of east). <---- need help for this
ok i need help on #2, here's my work...
155cos(22)i +155sin(22)j
270sin(42)i +270cos(42)J
add those...
324.37i + 258.7j
arctan(y/x) = arctan(258.7/329.37) = 38 Degrees <--- my answer... What am i doing incorrectly? (please help within the next 5 hours if you can, that's when the homework is due). thanks
