Does anybody know anything about measuring Angles I need help?

yes I can help please

let's take the example 2

x° and 68° forms right angle so it's 90°

so we'll add them to find x

x° = 90°- 68° = 22°

answer: hey there,

the answer you are looking for is a..

hope this you!

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°
