A 10 m long ladder leaning against a wall reaches a height of 8 m up the wall. What angle does the bottom of the ladder make with the ground? Round to the nearest degree.

Answer 1

To find the angle that the ladder makes with the ground, we can use trigonometry.

Let's denote the angle as θ. The opposite side of the triangle is 8 meters (height up the wall), the adjacent side is 10 meters (length of the ladder), and the hypotenuse is the ladder itself.

Using the cosine function:
cos(θ) = adjacent/hypotenuse
cos(θ) = 10/10
cos(θ) = 1
θ = arccos(1)
θ = 0 degrees

Therefore, the angle that the bottom of the ladder makes with the ground is 0 degrees.
