A right triangle has a hypotenuse length of 13 units. One leg has a length of 12 units. Which equation can be used to determine the length of the other leg?Group of answer choicesLaTeX: a^2=12^2+13^2 a 2 = 12 2 + 13 2LaTeX: a=\sqrt{13^2-12^2} a = 13 2 − 12 2LaTeX: a^2=12^2-13^2 a 2 = 12 2 − 13 2LaTeX: a=\sqrt{12^2+13^2} a = 12 2 + 13 2
