Question

On a number line points X,Yand z are such that d ( X,y- 8,d (y,z) - 15 and d (X,z) -7 which of the points is between the other two ?

Answer 1

Answer:

X is between the other two points

d(y,z)=15,d(X,y)=8,d(X,z)=7

d(X,y)+d(X,z)=8+7=15

d(y,z)=15

so,

d(X,y)+d(X,z)=d(y,z)

so, betweeness exists

Y-X-Z or Z-X-Y

so,X is between the other two points
