You can put this solution on YOUR website!
You have 2 right triangles with a common side.
\n" ); document.write( "The common side is the shortest distance from the employee to
\n" ); document.write( "the other building.
\n" ); document.write( "Using the given data, I can say:
\n" ); document.write( "(1) $\"+tan%28+62+%29+=+a%2F60+\"$
\n" ); document.write( "(2) $\"+tan%28+23+%29+=+b%2F60+\"$
\n" ); document.write( "(3) $\"+a+%2B+b+\"$ = the height of the factory building
\n" ); document.write( "-----------------------
\n" ); document.write( "(1) $\"+1.8807+=+a%2F60+\"$
\n" ); document.write( "(1) $\"+a+=+112.844+\"$

\n" ); document.write( "Convert the decimal to inches
\n" ); document.write( " $\"+.312%2A12+=+3.7+\"$
\n" ); document.write( "The factory is 138 ft 4 in tall approximately
