How far from the base of a building must the bottom of a 15-foot ladder sit in order for it to make a 52 angle with the ground?
olga55 [171]

Answer:

9.2 ft

Step-by-step explanation:

The length of the ladder is 15 ft

The ladder makes an angle of 52° with the ground

The distance (x) from the base of the house to the foot of the ladder is given by;

\frac{x}{15} = cos 52°

x = 15 × cos 52° = 9.23492213 ft

Which equals to 9.2 ft (rounded off to tenth of a foot)
