Question

3. Determine the LENGTH of a segment with endpoints A(-2, 3) and B(-4, -5) ? * 5.7 O 8.2. O 1 10 O 100

Answer 1

We calculate AB, that is:

$AB(-8,\text{ }-2)$

Now, we solve for the lenght, that is :

$l=\sqrt[]{(-8)^2+(-2)^2}^{}\Rightarrow l\approx8.2$

We know now that the length is of 8.2 units.
