9. Surveying You have walked 21 m away from a tree. At that point the angle of elevation to the top of the tree is 75°. How tall is the tree? 10. Flight A large airplane (plane A) flying at 31,000 ft sights a smaller plane (plane B) traveling at an altitude of 28,000 ft. The angle of depression is 37°. What is the line-of-sight distance between the two planes? 11. Surveying When the sun’s angle of elevation is 41°, a building casts a shadow of 38 m. How high is the building? 12. Navigation From the top of a lighthouse 21 m high, a sailboat is sighted at an angle of depression of 6°.
