How wide is the river?

I am having a hard time understanding how this is set up.

Help please?

**Reiny**, Monday, April 13, 2009 at 9:19pmmy diagram looked like this :

two vertical lines, points A and B 400 yards apart on the left line, with A above B.

Point P on the other line, so that angle PBA = 28º and angle PAB = 32º (the supplementary angle to 180)

now find the perpendicular distance from P to AB.

Does that help?
