Question 1062584
*[Tex \LARGE \theta = 255] is between 180 degrees and 270 degrees. This lands the angle in quadrant 3 (Q3). Therefore, the reference angle *[Tex \LARGE \theta \ '] can be found using the formula below


*[Tex \LARGE \theta \ '  = \theta - 180]
*[Tex \LARGE \theta \ '  = 255 - 180]
*[Tex \LARGE \theta \ '  = 75]


Angle *[Tex \LARGE \theta] is shown in red while angle *[Tex \LARGE \theta \ '] is shown in blue.
