An angle that measures 300 degrees is called a "reflex angle." A reflex angle is an angle that is greater than 180 degrees but less than 360 degrees. In this case, a 300-degree angle is greater than a straight angle (180 degrees) but less than a full rotation (360 degrees).

An obtuse angle. - larger than 180 and smaller than 360
An angle of 300 degrees is a reflex angle
A reflex angle
The other three sides equal 300 (each). Hope you found this helpful! :)
if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.
