we have two triangles
\n" ); document.write( ":
\n" ); document.write( "we use proportions of the two triangles to solve for h
\n" ); document.write( ":
\n" ); document.write( "let h be the height of the building, then
\n" ); document.write( ":
\n" ); document.write( "(h / 90) = (1 / 0.75)
\n" ); document.write( ":
\n" ); document.write( "cross multiply fractions
\n" ); document.write( ":
\n" ); document.write( "0.75h = 90
\n" ); document.write( ":
\n" ); document.write( "h = 120 meters
\n" ); document.write( ":
