Depreciation is the decrease in value of an item. Three years ago, Aaron bought a computer for $930. The computer is now worth $570. Assuming the value of the computer depreciates linearly, what is its yearly depreciation?

$120

Step-by-step explanation:

930-570=360 (Price difference in 3 years)

360 divided by 3= 120 (Price difference for each of the 3 years)

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°
