The original price of the ticket is $81

The price goes up to $99.63 with taxes and fees,

In this problem

$81 represent the 100%

The percent increase on the ticket price is 23%

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°
