Given that slope =0.06.
The triangle is a right-angled triangle with base x and height y.
Here r is the length of the deck of the bridge.
y=the exact rise of the bridge.
x= the run of the bridge,
By using the Pythagorean theorem, we get the length r as follows.
Substitute x=50 and y=3, we get
The length of the bridge is 50.09.
