Question

if A(2,-1) ,B(-1,3) and C(6,7) are the vertices of triangle ABC, then what is the length of median through vertex B.

Answer 1

Answer:

triangle ABC , x1 =2. , x2= -1 x3 = 6

y1= -1 , y2=3, y3= 6

distance of AB =√( x2-x1 )2 + (y2-y1)2

=√(-1-2)2 + [3-(-1)] 2

=√(-3)2 +(3+1)2

=√9+ (4)2

=√ 9+ 16

√25
