It is to insure the experiment does not have bias.
Cafeteria ratio of Swiss cheese to cheddar cheese is 15:17.
Perry’s ratio of Swiss chess to cheddar cheese is 5:7.
Wrong ratio because 5 * 3 = 15 but 7 * 3 does not equal 17.
I'm not sure which numbers you are referring to, but 3 has the same absolute value as -3, and 7 has the same absolute value as -7, just for an example.
3n+(4n-15)=90
3n+4n-15=90
7n=105
n=105/7
n=15
---------------------
Angle LQK is 4n-15
If n=15
Angle LQK = 4(15) - 15
= 60 - 15
= 45
