## Surveyors Transit

**Can you solve this trig problem?**

*
*

*A surveyor is measuring the distance across a small lake. He has set up his transit on one side of the lake 130 feet from a piling that is directly across from a pier on the other side of the lake. From his transit, the angle between the piling and the pier is 55 degrees. What is the distance between the piling and the pier to the nearest foot? *

I cannot understand what to do. My main problem really is that I can't visualize the picture. :[

This problem is a little hard to visualize

look at that picture, i hope that helps you better understand this problem.

Now you should try the problem on your own.

You can check your answer with the work below:

We'll use the equation

tangent(angle) = opposite/adjacent

tangent(55º) = opposite/130

opposite=tangent(55º) x 130

opposite = 185.66 feet
