XY = 17.
Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.
It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus,

To solve this equation, square and add both of the terms on the right like this:

And then take the square root of both sides. Your final answer should be:
XY = 17.
Answer:
I would say A, binocular vision. ((Not sure though.))
Step-by-step explanation:
Process of elimination. Opposable thumbs could help, but not as much as being able to spot your prey from far away. And what does singular births and just being a mammal help with being a predator? The answer that makes most sense is A. Hope this helps.

Sin 44/20 = sin 61/×
x = 20 sin 61/sin 44
x = 25.18 in
