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.
Looks confusing in the way you put it.
Answer:
1/3
Step-by-step
he flips the coin three time and there is one side so 1/3
Answer is A, y = 65
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
The slope is 1/1
You can use rise over run
