Solution:
Complementary angles add up to 90° and supplementary angles add up to 180°
Let "a" be the required angle
Supplement of an angle = 180 - a
Complement of angle = 90 - a
The supplement of an angle is six times as large as the complement of the angle.
Therefore,
180 - a = 6(90 - a)
Simplify the above
180 - a = 540 - 6a
6a - a = 540 - 180
Combine the like terms
5a = 360
Divide both sides by 5
a = 72
Thus the measure of the angle to the nearest whole degree is 72 degrees
