Pls plz anyone i’ll pass the class

what's the question???

x = 3.721

Step-by-step explanation:

Since, the triangle is right triangle, we can use trignometery equations ;

In this case, we need to use tangent equation in perpendicular :

tan θ = opposite side / adjacent side

Where , we've

tan 28 ° = x / 7

7 × tan 28 ° = 7 × x / 7 ..( Multiply each side by 7 )

7 × tan28° = x

Rewrite

x = 7 tan ×28°

multiply to get

x = 7 × 0.531709432

x = 3.72196602

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°
