Answer:
25.8°
Step-by-step explanation:
The wall is vertical so it makes 90° with the ground.
The ladder forms a right triangle of base = 45 ft and hypotenuse = 50 ft
To find the angle (x) the ladder makes with the ground:
Cos x = [tex]\frac{45}{50}[/tex] = 0.9
[tex]Cos^{-1}[/tex] 0.9 = 25.8° (answer rounded up to nearest tenth)
