Step-by-step explanation:

Expanded Notation Form:

30 + 8 + 0.6 + 0.05

Word Form:

Thirty-eight and sixty-five hundredths

In terms of place value, the decimal number can also be written as:

(2 x 1000)+ (3 x 100)+ (4 x 10)+ (5 x 1) . (8 x 0.001)+ (7 x 0.01)+ (6 x 0.1)

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.
