Andrei has a glass tank that he would like to fill with marbles and water.
W(m) models the amount of water Andrei needs (in liters) if he uses m marbles.
When does the necessary amount of water decrease faster?

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
