What is the area of a rectangle with width 2/5 in. and length 3/5 in

1/5 in²

6/25 in²

6/10 in²

2 in²

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

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.
