-180-30 = -210 degrees
Suppose the measure of the angle is x then its supplement is 180 - x x = 180 - x + 30 = 210 - x 2x = 210 => x = 105 degrees (supplementary angle = 75)
since 1 radian = 180/π degrees 210 degrees = 210/180 * π radians = 7/6 * π radians = 3.665191429...
It could be, but it never is. If you start at zero and travel 210 degrees of longitude in one direction, that brings you to the place that you could have reached by traveling only 150 degrees in the other direction. Halfway around is 180 degrees, so that's as high as longitude is ever marked, because if you go more than 180 degrees, then it would have been shorter to go less than 180 degrees the other way.
A longitude of 210 degrees means that you are measuring longitude from 0 to 360 degrees, which is fine, but very often people use -180 to +180 degrees, also called 180 degrees west to 180 degrees east instead. 210 degrees longitude is the same as 150 degrees west. You would pass French Polynesia and you would then make a landfall in Alaska in the USA which is in North America.
The maximum degree of longitude is 180 degrees east and west, so 210 degrees longitude is impossible.
An angle that is 210 degrees would be considered a "Reflex" angle. This is because its measurements exceed 180 degrees. Anything above 90 degrees is "obtuse". Once you hit 180 it becomes a "straight" line and anything above that is a "reflex".
With great difficulty because to get back where you started from you add 180 degrees clockwise and 300+180 = 480 degrees which is impossible but if you meant 30 degrees then the back bearing will be 30+180 = 210 degrees
225 degrees
-223 degrees Celsius is colder than -210 degrees Celsius.
Suppose the angle is x degrees. Then its supplement is 180 - x and complement is 90 - x So 180 - x + 90 - x = 210 ie 270 - 2x = 210 so 2x = 60 or x = 30
It is closer to 180. It is 11 from 180 and 19 from 210.
