Enter the rational number as a decimal. Then tell whether the decimal is a terminating or a repeating decimal. 1/5 =

The decimal is...
A - repeating
B - terminating

1/5 = 0.2, which is a terminating decimal

Step-by-step explanation:

1 ÷ 5 = 0.2, this is a terminating decimal because it does not go on forever like a repeating decimal.

Hope this Helps! :)

-SGO

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.
