1. The problem statement, all variables and given/known data An aircraft travels 250 km on a heading of 330 degrees. It then turns dues east and travels 420 km. How far and on what heading did it end up from its starting point? 2. Relevant equations Sine/cosine/tangent equations Pythagorean theorem 3. The attempt at a solution I have converted the 330 heading into our mathematically calculated angle of 30 degrees. I know it sounds silly, but I am stuck trying to draw a diagram. What direction was the aircraft heading initially? It would seem that it was heading Northwest(I finally figured that as I typed) but does converting it to the 30 degree angle change the direction? Thank you in advance!
