Two angles are complemtary. The large angle is 1 less than 6 times the smaller angle. which system could be used to determine the larger angle X and the smaller angle Y?

Answer 1

Let X be the larger angle and Y the smaller. Your system of two equations is:

X + Y = 90 (degrees)
X = 6Y - 1

7Y - 1 = 90
7Y = 91
Y = 13
X = 90 - 13 = 77
