Step-by-step explanation:

To find the average, add up all of the values and then divide by the number of values.

So first, add (-5) + (-4) + (-7) + (-2) + (2) + (5)

You get -11. Then, divide -11 by the number of values (6)

-11/6 is about -1.83, which rounds to -2

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°
