You can use similar right triangles for this problem.
\n" ); document.write( "In similar triangles, corresponding sides are proportional.
\n" ); document.write( "The first right triangle is formed by the height of the fountain (4') and its shadow (15').
\n" ); document.write( "The second right triangle is formed by the height of the flag pole (h) and its shadow (180').
\n" ); document.write( "So, from this you can write the proportion:
\n" ); document.write( " $\"4%2F15+=+h%2F180\"$ Solve this for h, the height of the flag pole.
\n" ); document.write( " $\"4%28180%2F15%29+=+h\"$
\n" ); document.write( " $\"h+=+48\"$ feet.
\n" ); document.write( " \n" ); document.write( "
