C: Solving More Complicated Problems Involving Right Triangles

Some problems require additional steps and often involve the use of multiple right triangles. It is sometimes useful to state the measurement you are trying to find and then decide what additional information is required to determine that measurement. A good habit is to add any calculated values to the diagram as you go.

Some problems will refer to an angle of depression or an angle of elevation.

Angle of Depression
The angle between the horizontal and an observer's line of sight to an object below the horizontal

Angle of Elevation
The angle between the horizontal and an observer's line of sight to an object above the horizontal
