A 12 foot ladder is leaning against a wall. Find the distance from the base of the wall to the top of the ladder, if the ladder makes an angle of 44 ° with the ground.

8.34 ft

Step-by-step explanation:

the base of the wall to the top of the ladder: sin 44° = x / 12

x = 12 x sin 44° = 12 x 0.695 = 8.34 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°
