Answer:
☆The length of the missing side is 5.
.
Step-by-step explanation:
☆Remember, Pythagorean theorem!
It looks like: [tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
.
☆All we need to do is plug in!
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {a}^{2} + {12}^{2} = {13}^{2} \\ {a}^{2} + 144 = 169 \\ \frac{\: \: \: \: \: \: \: \: - 144 = - 144}{ {a}^{2} = \sqrt{25} } \\ a = 5[/tex]
☆Therefore the value of A is 5.
