Ladder Problems
Use sin, cos, tan to find ladder length and placement distance — Identify opposite/adjacent, use sin θ = height/ladder, cos θ = base/ladder, tan θ = height/base
Height Observation
Calculate heights using angle of elevation from a distance — Draw right triangle, use tan θ = (top height − eye level)/horizontal distance
Multiple Heights
Find unknown heights when objects are stacked vertically — Solve base distance first, then use tan for each top to combine heights
Depression Angles
Look downward from tall buildings using alternate angles — Angle of depression at top equals angle of elevation at ground; tan θ = height/horizontal distance
