Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
An angle that measures 210 degrees is a reflex angle.
285 :)
The third angle measures 18 degrees.
A right angle measures 90 degrees
if an angle measures 30 then it is acute
the measures of each angle in a dodecogon is 360
An angle that measures 180 degrees is a straight angle, or straight line.Line.
An angle that measures 180 degrees would be in a straight line. Therefore, this angle is known as a straight angle.
285 minutes is equal to the following:4 hours, 45 minutes, 0 seconds17,100 seconds4.75 hours
An angle that measures to precisely 90o is called a right angle.
Angle greater than 180 degrees are reflex angles.
