Question
A student stands 12 m from a tower. Her eye level is 1.6 m and the angle of elevation is 45°. Find the tower height.
Which vertical length is opposite the 45° angle?
What you will learn
Model an angle of elevation from the observer eye line and distinguish the tangent-triangle height from total object height.
Common mistake to avoid
Using the entire object height as the opposite side ignores that the horizontal sight line begins at the observer eye level.
