Step-by-step explanation:

" To express the set in roster form the elements of a set are listed within the curly brackets and are separated by commas " .

We are given a statement as:

" The set of natural numbers less than 7" is represented in roaster form as:

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°
