An architect plans a wheelchair ramp with a vertical rise of 0.5. Safety regulations state that the angle of elevation must be 8°. how long will the tamp be to meet code?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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°
