Step 1
In this case, we have a right triangle formed by the ladder, the ground, and the building. The angle between the ladder and the ground is given as θ (degree angle). The ladder is the hypotenuse of the triangle, and we need to find the length of the base of the Show more…

A ladder 20 feet long leans against the side of a building, and the angle between the ladder and the building is $22^{\circ}$ (a) Approximate the distance from the bottom of the ladder to the building. (b) If the distance from the bottom of the ladder to the building is increased by 3.0 feet, approximately how far does the top of the ladder move down the building?
