 P: 555 Hi all, Would a heading of 330 degrees be equivalent to a standard angle measurement of 30 degrees? I'm used to calculating by subtracting the heading from 90, but the angle is too large for this problem. I know it seems to be a ridiculously simple question compared to others on this forum, but it's fairly difficult to find information about headings vs. standard on the internet. Thanks!

I'm unfamiliar with your use of 'standard angle' measurement. But as for how a heading is measured, this should answer that detail: http://en.m.wikipedia.org/wiki/Course_(navigation)

Does that help?

A "heading" of 0 or 360 degrees is due north. 330 degrees is 360- 330= 30 degrees "west of north".
