Answer: it will take 14 months for their weights to be the same.
Step-by-step explanation:
Let x represent the number of months it will take for their weights to be the same.
Katy weighs 105 pounds and is gaining 2 pounds a month. This means that the total weight of Katy after x months is
2x + 105
James weighs 175 pounds and is losing 3 pounds a
month. This means that the total weight of James after x months is
175 - 3x
For their weights to be the same, it means that
2x + 105 = 175 - 3x
3x + 2x = 175 - 105
5x = 70
x = 70/5
x = 14

Answer below
Step-by-step explanation:
Angle C can be found using triangle properties of subtracting all the known angles
C = 180 - 86 - 31
=63 degrees
Now we can solve for everything else using sine law
b = 5.16 m
c = 8.93 m
Since angles 6 and 2 are corresponding angles, that means that if they are congruent, we can say, through a converse theorem, that the lines which they lie on are parallel. Since, indeed, angles 6 and 2 are equal, then we can definitely see how the lines x and y are parallel.
