In triangle ABC, median AM is such that angle BAC is divided in ratio 1:2. AM is extended through M to D so that angle DBA is a right angle, then the ratio AC : AD is equal to
a median is a line joining a vertex with the mid-point of the opposite side
to find the value of and so that the graph of use given points (,) and (,)
...for (,)
....square both sides
...solve for
....eq.1
...for (,)
....square both sides
...solve for
....eq.2
from eq.1 and eq.2 we have
..solve for
now find
....eq.2
so, your equation is:
