Distance between the points (3 - 2 ) and (a,1 ) is 5 then the value of a is​

Answer»

Step-by-step explanation:

USING the DISTANCE formula we get

\sqrt{(x1 - x2) ^{2} +( y1 - y2) ^{2} } = d ^{2}

here

x1=3

y1=-2

x2=a

y2=1

d=5

On substituting these VALUES in the distance formula We get the VALUE of a=7 and a=-1
