Using the slope concept, it is found that the ladder reaches a height of 65.96 feet.
The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
In this problem:
Hence:
[tex]\tan{67^\circ} = \frac{h}{28}[/tex]
[tex]h = 28\tan{67^\circ}[/tex]
[tex]h = 65.96[/tex]
The ladder reaches a height of 65.96 feet.
