20 * 20 = 400
400 does not need to be rounded
Complementary angles are angles whose sum are equal to 90
degree. So
Let x be the one angle
And y be the second angle
X +y = 90
X – y = 90 -72 = 18
Adding the two equation
2x = 108
X = 54
Y = 90 -54 = 36 degrees is the smaller angle
9/12 is the answer, you can't simply then down anymore
