<h3>
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.

so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.
and y = 2, is just a horizontal line, check the picture below.
ANSWER = c. 63°
EXP:
>ABC = 1/2(x + y)
80 + 150 - 45= 185 (take away 45 as that was duplicated in the groups)
185/500= 0.37
