Acertain television is advertised as a 73-inch tv (the diagonal length). if the width of the tv is 48 inches, how many inches tall is the tv?

use Pythagorean Theorem to find the height with the diagonal is the hypotenuse, the width is a leg, then find the other one.

a^2+b^2=c^2

48^2 + b^2 = 73^2

b^2 = 3052

b=55

Therefore, the answer is 55

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°
