Determining a reasonable solution selpieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet belowsea level.7h – 5(3h - 8) = -72

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 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°

the diver is 33 feet below the surface.
