WHATS THE HEIGHT
WILL MARK BRAINLIST GOD BLESS

17 ft

Step-by-step explanation:

We can start by using the pythagorean theorem:

a^2 + b^2 = c^2

We are already given the hypotenuse as 18, and the legs as both 7 and h. We can substitute this in:

7^2 + h^2 = 18^2

49 + h^2 = 324

h^2 = 275

h ≈ 16.5831239518

This can be rounded to 17 ft

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°
