Help with trig please.
Two Δ are similar. The sides of the first Δ are 5, 10, and 15. The largest side of the second Δ is 20. Find the perimeter of the second Δ.

40 units

Step-by-step explanation:

Perimeter of the first triangle:

5+10+15 = 30

ratio of perimeters = ratio of sides

ratio of perimeters = 20:15 = 4:3

Perimeter of the second one: P

P/30 = 4/3

P = 40

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
