Angle <strong>of</strong> depression: The angle formed between the horizontal<br />
<strong>and</strong> the line <strong>of</strong> sight looking downwards.<br />
Angle <strong>of</strong> depression<br />
<br />
Drop: The difference in height between one end <strong>of</strong> an object <strong>and</strong><br />
the other end; equivalent to the rise.<br />
Example 2:<br />
The slope <strong>of</strong> a driveway must have a minimum angle <strong>of</strong> depression <strong>of</strong> 1<br />
to allow the surface water to drain away from the house. If the end <strong>of</strong><br />
a driveway is 8m from the house, how many cm does the driveway need<br />
to drop in order to maintain proper drainage<br />
Round your answer to 2 d.p.<br />
