It depends on compelement in what context.
In the unlikely event that it concerns angles measured in degrees, the answer is negative 25 degrees.
I say unlikely because if you need to ask this question, I am not sure you will understand what an angle with a negative measure means!
Assuming EBG are co linear, the complement of 65° is 115°
115 plus 115 = 230
1 × 115 = 115 5 × 23 = 115
The complement is 60 degrees.
10% of 115 = 10% * 115 = 0.1 * 115 = 11.5

The complement is 60 degrees.
10% of 115 = 10% * 115 = 0.1 * 115 = 11.5
25% of 115 = 25% * 115 = 0.25 * 115 = 28.75
85% of 115= 85% * 115= 0.85 * 115= 97.75
42% of 115= 42% * 115= 0.42 * 115= 48.3
ANSWER: 58.6551% of 115= 51% * 115= 0.51 * 115= 58.65
30% of 115= 30% * 115= 0.3 * 115= 34.5
31% of 115 = 31% * 115 = 0.31 * 115 = 35.65
47% of 115= 47% * 115= 0.47 * 115= 54.05
