An airplane has an airspeed of 145 km/h. it is to make a flight in a direction of 72 degees while there is a 32-km/h wind from 342 degrees. what will the airplane's actual heading be?

2. Relevant equations

trig functions

3. The attempt at a solution

this is a calc3 class using the varberg 9th edition text book and the class uses an online program called math lab which is provided by the text book and therefore all the online material directly relates to the text... So im on chapter 11 dealing with vectors... Specifically 3D vectors... however this appears to be a 2D problem... i missed a problem similar to this on my online quiz... so i went to the online practice problems and found this problem... and i clicked the "help me solve this" button which takes you step by step to the solution... At this point i could see where i made mistakes in solving the quiz problem, but i dont understand why i was wrong so my first question is... They draw the plane flying 72 degrees from north in a NE direction... Why? why is it not 72 degrees from East? like you would do any other unit circle type problem?
