Hope this helps but I think the answers are:
Part A: 3%=3/100
Part B: 51%=51/100
Part C: 289%= 2 89/100
Part D: 325%= 3 1/4
This answer is 0.7037 that is the answer for this problem
It is a simple linear equation with one unknown, we can solve it:
17(x + 5) = 0
17x + 17*5 = 0
17x + 85 = 0
17x = -85
x = -85/17
x = -5
The answer is C because 5+85 is 90 and a complementary needs to add up to 90 degrees
