Question

If ad is the median of triangle abc whose vertices are a (-2,6) b (2,-1) c(8,7) find length of median

Answer 1

Answer:

Step-by-step explanation:

In BC

B(2,-1) and C (8,7)

We take D(x,y)

x=mx²+nx¹/m+n

x=8+2/2

x=5

y=my²+ny¹/m+n

Y=7-1/2

y=3

D(x,y)=D(5,3)

In AD

Lenght=√(x¹-x²)²+(y¹-y²)²

Ad=√{2-5)²+(6-3)

Ad=(-3)²+(3)²

Ad=√18

AD=3√2c.m.
