given:\r
\n" ); document.write( "\n" ); document.write( "first angle $\"70\"$
\n" ); document.write( "second $\"55\"$ \r
\n" ); document.write( "\n" ); document.write( "then third angle is $\"180-%2870%2B55%29=180-125=55\"$ \r
\n" ); document.write( "\n" ); document.write( "so, triangle is $\"isosceles+\"$ because two of the legs are the same, and it is divided in two triangles (one with angles $\"x\"$ and $\"70\"$ , the other with $\"55\"$ and potion of other $\"55\"$ angle)\r
\n" ); document.write( "\n" ); document.write( "then, angle $\"x\"$ is an $\"exterior\"$ angle for smaller triangle (with $\"+55\"$ and portion of other $\"+55+\"$ angle) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "by definition of exterior angle, $\"x=55\"$ +portion of other $\"+55+\"$ angle\r
\n" ); document.write( "\n" ); document.write( "so, conclusion is: $\"x%3E55\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
