Im really stuck on this............

Len [333]

Answer:

H is the Answer

Step-by-step explanation:

Apply distance formula.

$(x {}^{2 } - {x}^{1} ) {}^{2} + ( {y}^{2} - {y}^{1} ) {}^{2} = d {}^{2}$

where d is the distance.

$( - 5 - 7) {}^{2} + (0 - 5) {}^{2} =$

$- 12 {}^{2} + - 5 {}^{2} = {d}^{2}$

$\sqrt{169} = {d}^{2}$

$d = 13$
