un comerciante de madera compra doce arboles a $3,150 cada uno , paga $1840 por hacerlos talar , al transportarlos el almacén le cuesta $ 975 ,

¿a que precio le resulta cada arbol?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
