Question

If (2,0),(-5,0) and (a, 0) are collinear then the value of a is

Answer 1

if x(2,0)

. y(-5,0)

. z(a,0)

are colinear then the distance (X,Z)=d(X,Y)+d(Y,Z)

so pls find the distance of the above three and use the above formula to find 'a'

Answer 2

Step-by-step explanation:

A=(2,0)

B=(-5,0)

C=(a, 0)

x= 2

x2=-5

x3= a

y=0

y2=0

y3=0

AB=√[(x2-x)]2+[(y2-y)]2

BC= route X3 minus x-2 whole square plus sy3 minus Y2 whole square

CA= root x 1 - x 3 whole square + Y 1 minus y 3 whole square

applied this formulas and write your answer if you can't understand and you not get your answer then I will make again the remaining answer I think this will confirmly use for you
