A piece of wood 2m long is cut into three equal pieces. One of those pieces is then cut into four equal pieces. What fraction of the total length will one of the small pieces e, and how long is it?

10 you would take 50/ .2

step-by-step explanation:

b.-4 units

all you   do is count how many times you move

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.

step-by-step explanation: it is d
