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.
Answer:
C. 5x
Step-by-step explanation:
Answer:
t>-4
I’m not sure if this is right
let length of one piece = x
length of other piece = 236-x
one piece is three times the length of the other
x=3(236-x)
x=708-3x
4x=708
x=177
so first piece is 177 inches long and second piece is (236-177)= 59 inches long
