El jardín circular de Randy tiene un radio de 1.5 pies. Quiere rodear el jardín con un borde que le cuesta $0.73 por pie. ¿Aproximadamente cuánto le costará el borde

step-by-step explanation:

mean or average is 40.6

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

step-by-step explanation:

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.
