What are the exact values of a and b?

Option D

Step-by-step explanation:

This here is a 30 - 60 - 90 triangle, knowing that two of the angles are given to be 30 degrees, and 90 degrees.

By leg opposite to 30 degree angle, a should be 2 times less the length of the hypotenuse. In other words, the hypotenuse AB = 2x, while a = x, so a = 1 / 2 * hypotenuse ( AB ) = 1 / 2 * 10 = 5 units.

Now leg b has a length of x√3 by leg opposite to 60 degree angle, the 60 degree angles being m∠ABC. a = 5 units = x, so b should = 5√3,

a = 5, b = 5√3

Solution = Option D

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
