Algebra.Com's Answer #179521 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! c^2=a^2+b^2 \n" ); document.write( "is the formula for finding the hypotenuse of a right triangle.\r \n" ); document.write( "\n" ); document.write( "Think of the points as the ends of the hypotenuse of a right triangle. \n" ); document.write( "one leg (x) of the triangle goes from 4 to -3 \n" ); document.write( "so we subtract -3 from 4 \n" ); document.write( "and the other leg (y) goes from 3 to 0 \n" ); document.write( "so we subtract 0 from 3 \n" ); document.write( "so first we need to find the length of each leg of the triangle \n" ); document.write( "where a=4-(-3)=7 \n" ); document.write( "and b=3-0=3 \n" ); document.write( "substitute \n" ); document.write( "c^2=7^2+3^2 \n" ); document.write( "calculate squares \n" ); document.write( "c^2=49+9 \n" ); document.write( "add \n" ); document.write( "c^2=58 \n" ); document.write( "find square root \n" ); document.write( "c=sqrt(58)= abt 7.6 inches \n" ); document.write( " |
