the distance from point x to the centre of a circle is 10cm.
\n" ); document.write( " if the radius of the circle 6cm, calculate the length of the tangent from x to the point of contact with the circle
\n" ); document.write( ":
\n" ); document.write( "The radius of 6 is from the circle center to the point of contact of the tangent
\n" ); document.write( "A this point it forms a right angle with the tangent
\n" ); document.write( "The hypotenuse = 10 cm, radius is one side, 6 cm
\n" ); document.write( "Let s = dist of x to the point of contact, use the pythag
\n" ); document.write( "s^2 + 6^2 = 10^2
\n" ); document.write( "s^2 = 100 - 36
\n" ); document.write( "s^2 = 64
\n" ); document.write( "s = \"sqrt%2864%29\"
\n" ); document.write( "s = 8 cm is the dist from x to the point of contact
\n" ); document.write( "
\n" );
