the answer

b. they are parallel and will never intersect.

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

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°

where is the option given
