A ladder 5 m long, leaning against a vertical wall makes an angle of 65° with the ground. How far up the wall is
the top of the ladder?

Step-by-step explanation:

length of ladder =5 m

Angle formed = 65°

Let h be the Height of the top of the ladder from the ground

Height of the top of the ladder from the ground

SOH-CAH-TOA

Since the hypotenuse side is given and what we are to solve is the opposite side, use SOH

Please refer to the photo for the illustration

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°
