Answer:
No, it is not tangent
Explanation:
XY can only be tangent to the circle if it forms a right angle to the diameter. To test this, you need to figure out whether the three parts of the triangle make a Pythagorean triple. 8.5×2=17, and 17^2+5^2 is 314, which is not equal to 20 squared. Therefore, it is not tangent. Hope this helps!
