\fA boat is heading towards a lighthouse, whose beacon-light is 10'}r feet above the water. From point A, the boat's crew measures the angle of elevation to the beacon, 120, before they draw closer. They measure the angle of elevation a second time from point B at some later time to be 20. Find the distance from point A to point B. Round your answer to the nearest foot if necessary. \f\fSolve for m. Round to the nearest tenth of a degree, if necessary. 5-5 F Answer: LI: : D Solve for m.

The angle of elevation to a nearby tree from a point on the ground is measured to be 490. How tall is the tree if the point on the ground is 53 feet from the tree? Round your answer to the nearest hundredth of a foot if necessary. From the observation deck of a skyscraper, Iavaughn measures a 42':1 angle of depression to a ship in the harbor below. If the observation deck is 8:2 feet high, what is the horizontal distance from the base of the skyscraper out to the ship? Round your answer to the nearest hundredth of a foot if necessary. Grace is trying to nd the height of a radio antenna on the roof of a local building. She stands at a horizontal distance of 21 meters from the building. The angle of elevation from her eyes to the roof [point A) is 24, and the angle of elevation from her eyes to the top of the antenna (point B ) is 420 . If her eyes are 1.54 meters from the ground, nd the height of the antenna (the distance from point A to point B ) Round your answer to the nearest tenth of a meter if necessary
