Since this is a right triangle, you can use the pythagorean theorem,
, to find XY. Since we know that 15 and 17 are our legs and that XY is the hypotenuse, we can solve it as such:

In short, XY is √514, or 22.67 rounded to the hundreths, units long.
I'm not 100% sure, but I'm pretty sure it's 1/12, 1/12, 1/12, 1/12
Since all you’re saying is evaluate ∫12–2
I’m assuming the answer would be 1/(1+x)(1-x)
Answer:
Concurrent as my perception
The unsimplified fraction is 8/12 which can be reduced to 2/3
