Problem
Solution
For this case we can set up the following notation
x= represent the measure of the first angle
y= represent the measure of the second angle
We also know that x= 5y
And since are complementary we need to satisfy this:
x +y = 90
5y +y= 90
6y = 90
y= 90/6 = 15
And solving for x we got:
x = 5*15 = 75
then the best solution is:
(2) 15º and 75º
