Question

A 25-ft ladder and then you can get inside of a house the bottom of the ladder is 8 ft away from the bottom of the house what is the measure of the angle formed by the bottom of the ladder and the ground round to the nearest degree

Answer 1

`71.33` degree

Explanation:

The angle between the bottom of the ladder and the ground is given by

`cos\alpha = (B)/(L)`

Where

B = distance between wall of house and the foot of ladder

L = Length of the ladder

Substituting the given values we get -

`Cos \alpha = (8)/(25)\\Cos \alpha = 0.32\\\alpha = Cos^(-1)(0.32)\\\alpha = 71.33`
