Answer:
x=15
Step-by-step explanation:
Radius is 8 since thee short leg is 8 and it is from the center to the ed of the circle. 9 is the length of the hypotenuse from the tip of the triangle to the edge of the circle. The rest is equivalent to the radius which is 8. So hypotenuse is 17, short leg is 8. Now we have what we need to find x. We can do this by using the formula A^2+B^2=C^2.
8^2=64 C^2=289
289-64=225
225 square root is 15
so x=15

Answer: 46 pounds</h3>
===============================================
Work Shown:
N = weight of Noah's dog = 15 & 1/3 pounds
A = weight of Aiden's dog = unknown
A = 3*N
A = 3*(15 & 1/3)
A = 3*(15 + 1/3)
A = 3*15 + 3*(1/3) .... distribute
A = 45 + 1
A = 46
Aiden's dog weighs 46 pounds.
