Ijust need someone to do the work and the process, but i know the answer

8 yd

Step-by-step explanation:

The area of the square is found by the equation: A = s², where s is the length of a side.

Since we know the area, we can plug that number in: 64 = s²

Square root: ±√64 = s

Simplify: s = 8 yd (no negatives because distances must be > 0)

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°
