Aladder leans agaisnt a building that is perpendicular to the ground such that it makes a 74 degree angle with the ground and its bottom lies 2.75 feet from the base of the buidling

Gee there's no question there but I guess you want to know
1) How far up the building the ladder goes and
2) the length of the ladder.
tangent (74) = building height / 2.75
building height = 2.75 * 3.4874
9.59035 (the point on the building where the ladder touches the building)

2) cosine (74) = 2.75 / ladder
ladder = 2.75 / 0.27564
9.976781309 (the length of the ladder - about 10 feet)
