**drwls**, Saturday, December 17, 2011 at 10:00pmIgnore the data on the first rope. You don't need it.

The distance from a point to a line is the distance from the point along a perpendicular to the line.

Draw the figure.

The horizontal distance from the point below the balloon to the second rope ground support point is 18/tan30.

Multiply that by sin30 for the answer.

The answer is 18 cos 30 feet.

I don't see anything about physics here.
