Algebra.Com's Answer #61424 by ganit(6)![]() ![]() ![]() You can put this solution on YOUR website! In a 90-60-30 triangle the shortest side will be the side opposite the smallest angle. \n" ); document.write( "The side opposite 30 angle will be the shortest one.\r \n" ); document.write( "\n" ); document.write( "We can use the sine ratio. \n" ); document.write( " now, sin 30 = opp side / hypotaneus \n" ); document.write( " 1/2 = opp side / 18 \n" ); document.write( " hence opp side = 9 \n" ); document.write( "That is the length of the shortest side. \n" ); document.write( " |
