A ladder 9.00 m long leans against the side of a building. If the ladder is inclined at an angle of 75.0° to the horizontal, what is the horizontal distance from the bottom of the ladder to the building?

The ladder makes a right triangle ABC with the building, where A is the bottom of the ladder, B is a right angle (wall with ground) and C is the top of the ladder.
Now AC = 9 m. and CAB = 75 degrees.
We know that
AB/AC = cos(75) and AC is known.
So AB = AC cos(75) = horizontal distance to the wall.
Now AC = 9 m. and CAB = 75 degrees.
We know that
AB/AC = cos(75) and AC is known.
So AB = AC cos(75) = horizontal distance to the wall.
