During a total eclipse of the sun, the moon is directly in line with the sun and blocks the sun's rays. The distance ED between Earth and the moon is 240,000 miles, the distance DA between Earth and the sun is 93,000,000 miles, and the radius AB of the sun is 432,500 miles.

a. Copy the diagram and label the known distances. 

b. In the diagram, ΔBDA ~ ΔCDE. Use this fact to explain a total eclipse of the sun. 

c. Estimate the radius CE of the moon.
