The legs in an isosceles right triangle measure 5 units more than twice the measure of the third side.
\n" ); document.write( " Find the measure of each side of the triangle if the perimeter is 30.
\n" ); document.write( ":
\n" ); document.write( "I don't think this can be a \"right triangle\"
\n" ); document.write( ":
\n" ); document.write( "Let x = the third side
\n" ); document.write( "then it say,\"legs in an isosceles triangle measure 5 units more than twice the measure of the third side\"
\n" ); document.write( "2x + 5 = legs of the isosceles triangle
\n" ); document.write( ":
\n" ); document.write( "The three sides = 30
\n" ); document.write( "2(2x+5) + x = 30
\n" ); document.write( "4x + 10 + x = 30
\n" ); document.write( "4x + x = 30 - 10
\n" ); document.write( "5x = 20
\n" ); document.write( "x = $\"20%2F5\"$
\n" ); document.write( "x = 4 units is the 3rd side
\n" ); document.write( "then
\n" ); document.write( "2(4) + 5 = 13 units are the other two sides
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check: 13+13+4 = 30 \n" ); document.write( "
