In the main lobby of the hotel, there is a circular hospitality area that also rotates. The radius of the hospitality area is 3 m. The distance from the front door, at point A, to the far side of the hospitality area, at point C, is 20 m. At a certain moment the dessert bar is located at point B and the tourist information desk is located at point E. B, E 6. Assuming AB and AE are tangent to the circle, find CD and AD. Explain how you arrived at your answers.

Coordinate Geometry

Coordinate geometry, also known as analytic geometry or Cartesian geometry in classical mathematics, is a type of geometry that is studied using a coordinate system. Coordinate geometry is a branch of mathematics that describes the position of points on a plane using an ordered pair of numbers called coordinates.
