Answer 2

Primero hallar el lado que falta

Lado: a

Mediante el teorema de pitagoras:

${12}^{2} + {a}^{2} = {13}^{2} \\ 144 + {a}^{2} = 169 \\ {a}^{2} = 169 - 144 \\ {a}^{2} = 25 \\ a = \sqrt{25} \\ a = 5$

Calcular:

$m = 13( \frac{12}{13} ) + 5( \frac{12}{5} ) \\ m = 12 + 12 \\ m = 24$

Respuesta: M=24
