The angle that this ladder would make with the ground is equal to 63.64°.
How to determine the angle that the ladder make?
In order to determine the angle that this ladder would make with the ground, we would apply Cosine trigonometric. Mathematically, this is given by this expression:
Cosθ = Adj/Hyp
Substituting the given parameters into the formula, we have;
Cosθ = 8/18
Cosθ = 0.4444
θ = cos⁻¹ (0.4444)
θ = 63.64°
