Question 1081838
Alpha is quadrant 3 (Q3) so alpha is between 180 degrees and 270 degrees.


Beta is quadrant 1 (Q1) so beta is between 0 degrees and 90 degrees.


Let gamma = alpha-beta


The variable gamma is restricted with this inequality 90 < gamma < 270


The lower bound of 90 is from the fact that alpha - beta = 180-90 = 90 (where alpha = 180 and beta = 90)


The upper bound of 270 is from the fact that alpha - beta = 270-0 = 270 (where alpha = 270 and beta = 0)


So the angle gamma, aka alpha-beta, is <font color=red>located in quadrant 2 or in quadrant 3</font>.
