Homework Statement
A plane leaves the airport in Galisteo and flies 170km at 68 degrees east of north. And then flies 230 km at 48 degrees south of east. It makes an emergency landing at it's pasture. When the airport sends out a rescue crew, in which direction and how far should they go to fly directly to the plane?
Homework Equations
X and Y components, Vector addition.
The Attempt at a Solution
170(cos68deg) = x comp = 63.7km
170(sin68deg) = y comp = 157.8km
230(cos48deg)=x comp = 153.9km
230(sin48deg)=y comp = 171km
Rx=217.6km
Ry=328.6km
R= 394.1km, by calculating the magnitude
Ry/Rx (arctan) = 56.5 degrees
394.1km at 56.5 degrees West to get to the plane.
