Question

Si A D.P B en el siguiente cuadro, calcule

m+n+a.​

Answer 1

Respuesta:

$\frac{30}{5 0 } = \frac{a}{15} \\ \frac{{3} }{5} = \frac{a}{15 } \\ \frac{45}{5} = a \\ 9 = a$

$\frac{30}{5 0 } = \frac{21}{m} \\ \frac{{3} }{5} = \frac{21}{m} \\ {3m} = 105\\m = \frac{105}{3} \\ m = 35$

$\frac{30}{5 0 } = \frac{n}{n + 8} \\ \frac{{3} }{5} = \frac{n}{n + 8 } \\ 3n + 24 = 5n \\ 5n - 3n = 24 \\ 2n = 24 \\ n = 12$

$- - - > m + n + a \: = 35 + 12 + 9 = 46$
