You can put this solution on YOUR website!
in right triangle we know one angle is 90 degrees
\n" ); document.write( "but we also know that the sum of measures of the three angles in a triangle is 180 degrees\r
\n" ); document.write( "\n" ); document.write( "also given one angle is 45 degrees\r
\n" ); document.write( "\n" ); document.write( "so the measure of third angle is:\r
\n" ); document.write( "\n" ); document.write( "x + y + z = 180
\n" ); document.write( "let x = 90 and y = 45
\n" ); document.write( "90 + 45 + z = 180
\n" ); document.write( "z = 180 - 45 - 90 = 45 \r
\n" ); document.write( "\n" ); document.write( "so the three angles are 45, 45, 90\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter of triangle = a+ b + c
\n" ); document.write( "a = 4 m ;b = 2.3 m ;and c = 3.7m
\n" ); document.write( "perimeter = 4+2.3+3.7 = 10 m\r
\n" ); document.write( "\n" ); document.write( "
