Answer:
Step-by-step explanation:
Differentiating, you get ...
... x·dy +y·dx +dx +dy = 2x·dx +2y·dy
Collecting terms gives ...
... dy(x +1 -2y) = dx(2x -y -1)
... dy/dx = -(2x -y -1)/(2y -x -1)
SOLUTION
Draw the diagram
a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
Hence
SInce AC=30, Then
Thus, from the median properties of a triangle, AB = 15
