The table shows the progress of a plant's growth. The height of the plant, y, is given by the table, where x is the number of days. Which statements are correct?
A)
The rate of change is 2 cm.
B)
The plant's height at 10 days is 30 cm.
The plant's height at 30 days is 40 cm.
D)
The initial height of the plant is 0 centimeters high.
E)
The plant's growth can be modeled by the equation y-2x+10.

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.

believe it or not anna is correct good job anna give me a fist bump there u go gal
