Answer:

El soluccion es 20m.

Step-by-step explanation:

Para encontrar la base major necesitas saber el area, la altura, y el base menor.

Puedes usar la formula para la area de un trapecio: [tex]A=\frac{a+b}{2} *h[/tex]

Pero se puede cambiar por lo que es en términos de encontrar la base más grande:

[tex]b=2\frac{A}{h} -a\\A=Area\\h=altura\\a=base-menor\\b=base-major[/tex]

Y si conectas las variables que conoces, siempre podrás encontrar la que no tienes

[tex]b=2\frac{120}{8} -10\\b=20[/tex]
