Question 1155572
angle of 8.7 degrees northeast
-----------
IDK what that means.
I'm familiar with angles on the x-y plane, and headings given using North as 360 or 000 degrees, increasing clockwise, but not 8.7 degs NE.
=============
People who don't know what they're talking about should not attempt to compose math problems.
Or anything else.
=================
There is a wind blowing southeast at 20 miles per hour. 
Wind info by ATC or towers is given as the direction it is from.
This would be "winds are 135 at 20" - ignoring the mi/hr.  (Aircraft use knots.)
Is that the case here? Is the wind from the southeast?
