Answer:
TY = 60
D is correct
Explanation:
In triangle TUV, Y is the centroid.
As we know the centroid of the triangle is divides median into 1:2 ratio. The ratio is length of median from centroid to the side to length of median to opposite vertex.
Therefore, WY:TY = 1:2

where, WY=30



Hence, The length of TY is 60
