Algebra.Com's Answer #15408 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! The two isosceles triangles are \"similar\" so their sides are \"proportional\" \n" ); document.write( "Find the scale factor by dividing the known length of one side of the larger triangle by the known length of a \"corresponding\" side of the smaller triangle.\r \n" ); document.write( "\n" ); document.write( "Scale factor is: 8\"/2\" = 4\r \n" ); document.write( "\n" ); document.write( "Multiply the length of the base of the smaller triangle by the scale factor of 4 to find the unknown length of the base of the larger triangle.\r \n" ); document.write( "\n" ); document.write( "Base of smaller triangle = 3\" \n" ); document.write( "Base of larger triangle = 4 X 3\" = 12\" \n" ); document.write( " |
