1. Applications of Right Triangles LG: I can apply my knowledge of right triangles to solve problems based on realistic situations

2. Terms to know: – “ Angle of elevation” – angle measured from the horizontal up to an object – “Angle of depression” – angle measured from an object down to the ground

3. Application Example 1 A statue casts a shadow 67m long. If the sun’s rays form an angle of 63° with the ground, determine the height of the statue to one decimal place.

4. Application Example 2 A 7 ft ladder is leaning against a wall. If safety regulations require the ladder to be 2 ft from the wall, what angle does the ladder make with the ground?

5. Application Example 3 A small plane is flying at an altitude of 3500m toward an island. The angle of depression to the island is 18°. How much farther, to the nearest kilometer, does the plane need to fly before it is directly above the island?
