10. 10. GEO Lesson 8-4 Lesson Quiz 8-1 8-4 Homework D 8-1 A 310-313 NB Page 296-299 TB Page CIOs Notes Reﬂections 8-4 Reﬂection Questions#1. Why is the angle of depression from a light house to a boat the same as the angle ofelevation from the boat to the light house? The angle of depression from the lighthouse and the angle of elevation from the boat are alternate interior angles formed by the line of site (the transversal) and the parallel horizontal lines.#2. What strategy is used to solve angle of elevation and depression problems?#3. Comment on who might use trigonometric ratios to solve angle of depression andelevation problems and how? 5

The angle of depression from the lighthouse and the angle of elevation from the boat are alternate interior angles formed by the line of site (the transversal) and the parallel horizontal lines.#2. What strategy is used to solve angle of elevation and depression problems? Trigonometric ratios can be used to solve angle of elevation and depression problems. Occasionally, the Pythagorean formula can be used.#3. Comment on who might use trigonometric ratios to solve angle of depression andelevation problems and how? 5

Pilots, control tower operators, ﬁre foresters, and surveyors all might use trig ratios to determine the height or distance of an object. 5
