Answer:
D
Step-by-step explanation:
The centroid of a triangle is the intersection of the three medians of the triangle (each median connecting a vertex with the midpoint of the opposite side).
So the equations are equal
X + y = 136
x = 3y - 16
3y - 16 + y = 136
4y - 16 = 136
4y = 136 + 16
4y = 152
y = 152/4
y = 38
x = 3y - 16
x = 3(38) - 16
x = 114 - 16
x = 98
the larger piece (x) = 98 ft and the smaller piece (y) = 38 ft
