Question

if the distance between the points (2, - 2 )and( -1, X) is 5 then one
of the value of x is​

Answer 1

Solution

the distance between the points (2, - 2 )and( -1, X) is 5

therefore....

$= > \sqrt{(2 + 1) {}^{2} + ( - 2 - x) {}^{2} } = 5 \\ = > 9 + ( - 2 - x) {}^{2} = 25 \\ = > - 2 - x = \sqrt{16} \\ = > - 2 - x = 4 \\ = > x = - 6$

the value of X is = -6
