Algebra.Com's Answer #574732 by dkppathak(439)![]() ![]() You can put this solution on YOUR website! The height of a triangle is 8 m less than the base. The area is 10 m squared. Find the height and base.\r \n" ); document.write( "\n" ); document.write( "let base is x m than height will be X-8 m \n" ); document.write( "area of triangle =10m^2 to find x =? \n" ); document.write( "area of triangle =basexheight/2 \n" ); document.write( "10=x(x-8)/2 \n" ); document.write( "20 =x^2-8X \n" ); document.write( "x^2-8x-20=0 \n" ); document.write( "x^2-10x+2x-20=0 \n" ); document.write( "(x+2)(x-10)=0 \n" ); document.write( "X=10 or x=-2 neglecting -2 so that x=10 \n" ); document.write( "base=10m and height will be 2m \n" ); document.write( " |
