Question

Suppose two 5-meter poles are fixed to the ground in upright position [in red], one in San Diego, CA and the other 435 miles due east near Phoenix, AZ. Assume both lie on the earths equator. Suppose at noon the pole in San Diego casts NO shadow, while the pole in Phoenix casts a shadow of 0.45 meters [in blue]. Based on this information and the diagram shown, select the true statement/s, assume r is unknown, and refers to the radius of the earth, assume approximations are acceptable where appropriate.
