**Anonymous**, Tuesday, February 7, 2012 at 5:50amI assume that the second window is 25 feet high.

Draw a diagram. Let the foot of the ladder be x feet from the first building, and y feet from the second building. Using the good old Pythagorean Theorem, we have

x^2 + 30^2 = 42^2

y^2 + 25^2 = 42^2

so, x=29.39 and y=33.75, so the street is roughly 63 feet wide.

I hope this is right. :D

*This is my illustration

i____\l

-the 'l' is the 1st building.

-the 'i' is the 2nd building.

-the "backslash(\)" is the ladder.

-the "underscore(_)" is the street.

**Anonymous**, Tuesday, February 7, 2012 at 11:44amYour diagram is wrong. The ladder does not reach from one building to the other. Its foot is somewhere in the middle of teh street, and it pivots so that it touches the first building at a height of 30', and the other at a height of 25'. Read the problem.
