A Ladder 24 Feet Long Leans Against the Side of a Building

A ladder 24 feet long leans against the side of a building, and the angle between the ladder and the building is $25 ^ { \circ }$ .
a) Approximate the distance from the bottom of the ladder to the building. Give the answer to one decimal place.
b) If the distance from the bottom of the ladder to the building is increased by 2 feet, approximately how far does the top of the ladder move down the building? Give the answer to one decimal place.

A) distance from the bottom of the ladder to the building $= 20.2$
Ladder movement $= 2.0$
B) distance from the bottom of the ladder to the building $= 20.2$
Ladder movement $= 1.0$
C) distance from the bottom of the ladder to the building $= 1.0$
Ladder movement $= 10.1$
D) distance from the bottom of the ladder to the building $= 10.1$
Ladder movement $= 1.0$
E) distance from the bottom of the ladder to the building $= 1.0$
Ladder movement $= 1.0$
