Question 411878: A plane traveling approximately southwest has a vector heading of 180mi/hr at 240 degrees. A partial headwind blowing northwest has a vector heading of 35mi/hr at 150 degrees.
required: what is the planes final vector heading including both the theta and the final displacement angle?
I am stuck can't get started, I missed the lecture. Test on Wed yikes!! please help!! thanks so much.

picture each vector as the hypotenuse of a right triangle made up of north-south and east-west components
using the unit circle and trigonometry , calculate the value of the components and add them
___ n-s plus n-s and e-w plus e-w
the summed values are the components of the resultant vector of the answer
use Pythagoras on the components to find the magnitude of the resultant , and use trigonometry to find the direction angle
