The dependent variable is money
35 would be the answer. 45+35=80 and 45 is 10 more than 35
What are you trying to figure out??
Let the angle be x and it's complement be c.
Then, x = c + 88 and x + c = 90
Substitute the first equation in the second.
(c+88) + c = 90
2c+88 = 90
2c = 2
c =1
Compliment = 1
Angle = 89
