8/11 written as a decimal

0.72727272727 or 0.73

Step-by-step explanation:

To get that all you have to do is divide 8 by 11. So 8 divided by 11 equals 0.72727272727 which would round up to 0.73

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.
