Let A(2,1) B(-4,5) C(-5,-2).

Find,

distance(A,B)=X

Find,

distance(A,C)=Y

Find,

distance(B,C)=Z

The answer is,

X+Y+Z

sqrt((1-7)^2+(-1-6)^2}=sqrt(36+49)=sqrt(85)5.Consider the two points (1,-1) and (7,6). The distance between them is:__

The x co-ordinate of the midpoint of the line segment that joins them is:___

The y co-ordinate of the midpoint of the line segment that joins them is: ___

The midpoint is,

(4,2.5)
