  5. Guiding question: What is the difference between the angles of elevation and depression?

  6. Trigonometry We can apply trigonometry to situations in the real-world! Angles of elevation The angle of elevation (AOE) is the angle your eyes make when you look up at an object.

  7. Angle of Elevation We can apply trigonometry to situations in the real-world! Angles of elevation The angle of elevation (AOE) is the angle your eyes make when you look up at an object.

  8. Angle of Elevation Suppose the angle of elevation from a rowboat to the light of a lighthouse is 35o. You know that the lighthouse is 96 feet tall. How far from the lighthouse is the rowboat?

  9. Angle of Elevation Suppose the angle of elevation from a rowboat to the light of a lighthouse is 35o. You know that the lighthouse is 96 feet tall. How far from the lighthouse is the rowboat?

  10. Angle of Elevation Suppose you live about 5.1 miles from a tower. From your home, you see a plane directly above the tower. Your angle of elevation to the plane is 21o. What is the plane’s altitude?

  11. Angle of Depression The angle of depression (AOD) is the angle your eyes make when you look down at an object.

  12. Angle of Depression The angle of depression (AOD) is the angle your eyes make when you look down at an object.

  13. Angle of Depression An airplane flying 3500 ft above ground begins a 2° descent to land at an airport. What is the horizontal distance from the plane to the airport when it starts its descent?

  14. Angle of Depression An airplane flying 3500 ft above ground begins a 2° descent to land at an airport. What is the horizontal distance from the plane to the airport when it starts its descent?

  15. Angle of Depression TB pg 575 Guided Practice 2 Vernon is on top deck of a cruise ship and observes two dolphins following each other directly away from the ship in a straight line. Vernon’s position is 154 meters above sea level, and the angles of depression to the two dolphins are 35o and 36o. Find the distance between the two dolphins to the nearest meter.
