A 32 foot ladder is leaning against a building and forms a 29.37 angle with the ground how far away from the building is the bas
Ber [7]

In the picture below, h is height of building and x is the distance the base of the ladder is away from the base of the building.

We use trigonometry to find x, particularly the cosine function.

cos(29.37°) = x/32

cos(29.37°)(32) = x

27.8870633052 = x

We now round off to the nearest hundredths, which means to two decimal places.

27.89 feet = x
