If mZDEC = (12x - 3), mZBCE =
kati45 [8]

Answer:

Step-by-step explanation:

12x - 3 = 180 - (7x - 26) supplementary angles

19x = 209

   x = 11

m∠DEC = 12(11) - 3 = 129°

m∠BCE = 7(11) - 26 = 51°

M∠ADE = 129 - 72 = 57°  exterior angle rule

m∠EDB = 180 - 57 = 123° supplementary angles

m∠DBC = 57° corresponding angle to ADE

the size of a red blood cell is 0.000007m and that of a plant cell is 0.00001265m show that a red blood cell is half of a plant
Readme [11.4K]

ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.

EXPLANATION:

<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>

\frac{0.00001265}{2} = 0.000006325 m

Therefore, half of a plant cell's size is 0.000006325 m.

<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>

0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
