Question

A (x,4),B (9,4) AB =10 units.find the value of x

Answer 1

you can solve it by using distance formula.

hope it may help you

Answer 2

$\sqrt{ {(x - 9)}^{2} + ( {4 - 4)}^{2} } = 10$

$\sqrt{ {(x - 9)}^{2} } = 10$

On squaring on both sides we get

${(x - 9)}^{2} = 100$

$x - 9 = 10$

$x = 19$

is ur answer
