Question

find the value of x such that a b is equal to BC where the coordinates of a b and c are (- 5,2),(1 ,- 2) and (X ,4) respectively.

please answer fast.​

Answer 1

Answer:

Since AB equals BC

$\sqrt{36 \: + \: 16} \: = \: \sqrt{ {(1 - x)}^{2} + 36}$

$\sqrt{52} = \sqrt{1 + {x}^{2} - 2x + 36}$

${x}^{2} - 2x - 15 = 0$

$x = 5$

OR

$x = - 3$
