Question
Find the distance between the origin and the point$:(-5, -12)$
✓
Answer
Co$-$ordinates of origin are $O\ (0, 0).$
$B\ (-5, -12)$
$\text{BO} =\sqrt{(0+5)^2+(0+12)^2} $
$ =\sqrt{25+144} $
$=\sqrt{169} $
$=13$
$B\ (-5, -12)$
$\text{BO} =\sqrt{(0+5)^2+(0+12)^2} $
$ =\sqrt{25+144} $
$=\sqrt{169} $
$=13$
