A pilot wishes to fly 400km north. Due to the wind, the pilot actually flies 430km in the direction N5E. How far, and in what direction must the pilot now fly in order to achieve the proper displacement?

Question

hero · Answer

What does N5E mean?

anonymous · Answer

north 5 degrees east

hero · Answer

That's a terrible way to write that. Should be $5^{\circ}$NE

anonymous · Answer

i dunno man, it's pretty standard. http://www.mathsteacher.com.au/year10/ch15_trigonometry/11_directions/23dir.htm

hero · Answer

Not exactly. There are other ways it is written. I've seen plenty math in my life. I've never seen it written that way. You shouldn't assume things like that.

hero · Answer

Plus, it looks like you're from another country. Austrialia maybe

anonymous · Answer

no i just googled that page.

hero · Answer

Anyway, not every book writes it that way.

anonymous · Answer

Let's not argue semantics.  You need to draw a triangle and solve for the degree measure of the proper angle.  (I'll draw it just give me a minute.)

hero · Answer

Nobody is arguing @CaptianPollux. We're just clearing up misunderstandings.

random question: does a linear combination have to include at least 2 terms? or can a single term be considered a linear combination?

|dw:1345570583760:dw|  You'd adapt it to a ight triangle problem and then use trig to find the proper angle.

hero · Answer

Linear Combination implies at least two lines and two equations and two variables x and y.

hero · Answer

I think your triangle is a little off @CaptianPollux 

I think it should be this:
