MGR4 (Map Grid Reference, 4) Four Grid Reference
If the reference points are not correct, the location of any coordinate will be incorrect.
draw two lines perpendicular to each other. theses line will act as reference line. starting from reference line plot the point to its position.
Since the angle of 331⁰ is in the fourth quadrant, then the measure of its reference angle in the first quadrant is 360⁰ - 331⁰ = 29⁰ .
Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
