ANOTHER WAY TO THE SOLUTION:
\n" ); document.write( "The sum of the measures of the interior angles in a polygon with $\"n\"$ sides is $\"%28n-2%29%2A180%5Eo\"$ .
\n" ); document.write( "In particular, the sum of the measures of the interior angles in a quadrilateral is $\"%284-2%29%2A180%5Eo=2%2A180%5Eo=360%5Eo\"$ .
\n" ); document.write( "The angles at A, and H are congruent (they have the same measure), because a kite is symmetrical, so if $\"A\"$ is the measure of those angles,
\n" ); document.write( " $\"A%2B135%5Eo%2BA%2B53%5Eo=360%5Eo\"$
\n" ); document.write( " $\"2A%2B135%5Eo%2B53%5Eo=360%5Eo\"$
\n" ); document.write( " $\"2A%2B188%5Eo=360%5Eo\"$
\n" ); document.write( " $\"2A=360%5Eo-188%5Eo\"$
