Answer 1

Answer:

5 units

Step-by-step explanation:

The points are:

$A(-2, 5)$

$B(-2, -7)$

$C(-6, -4)$

Considering the sides as vectors, we have:

$\overrightarrow{AB}, \overrightarrow{AC},\overrightarrow{CB}$

Once

$\overrightarrow{AC} = C - A =(-6, -4) -(-2, 5) = (-6+2, -4-5) = (-4, -9)$

$\overrightarrow{AB} = B - A =(-2, -7) -(-2, 5) = (-2+2, -7-5) = (0, -12)$

$\overrightarrow{CB} = B - C =(-2, -7) -(-6, -4) = (-2+6, -7+4) = (4, -3)$

$\Vert \overrightarrow{AC} \Vert = \sqrt{x^2 + y^2} = \sqrt{(-4)^2+(-9)^2} = \sqrt{16+81}= \sqrt{97}$

$\Vert \overrightarrow{AB} \Vert = \sqrt{x^2 + y^2} = \sqrt{0^2+(-12)^2} = \sqrt{144}= 12$

$\Vert \overrightarrow{CB} \Vert = \sqrt{x^2 + y^2} = \sqrt{4^2+(-3)^2} = \sqrt{16+9}= 5$
