Algebra.Com's Answer #47350 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Think about similar triangles in which corresponding sides are proportional. \n" ); document.write( "In one of the triangles, you have the height which represents the height of the tree and the base which represents the length of the tree's shadow. \n" ); document.write( "In the other triangle, you have the height which represents the metre stick and the base which represents the length of the stick's shadow. \n" ); document.write( "So, based on the above, we can write and solve a proportion in which h = the height of the tree. It goes like this: \n" ); document.write( "The height of the tree : the height of the metre stick as the length of the tree's shadow is to the length of the metre stick's shadow. \n" ); document.write( "In algebrese, this looks like: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "h = 25 metres. \n" ); document.write( " |
