Answer:
No.
Step-by-step explanation:
No, Bob is not correct.
The formula he's using is the following:

The important thing here is that the angle is between the two sides.
In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.
Either Bob needs to find the other side first or find the angle between 8 and 18.
Let one of those numbers be x.
Now,
according to question,
The other number must be,
3x-6
Now,
as said in the question,
x+3x-6 =62
4x -6 =62
4x = 68
x = 17.
Now,
we got one of those numbers which was x = 17,
and the other number should be 3(17)-6 = 51-6 = 45.
The percentage would be 27.5 because you add the 11, 5, 8, 7, 9 up and then divided by 11 to get your percentage. So percentage should be 27.5% and a fraction would be 11/40
