Question 6
The diagram below shows a red blood cell in three different concentrated environments. The best
environment for the red blood cell is Y.
x
Z
Spherical
Biconcave
Crenated
Explain what has happened to the blood cell in environment Z and explain why this has
happened in terms of osmosis:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: 800
