Here is a sketch. (I drew the triangle a little shorter than it should be, just to illustrate a point).
\n" ); document.write( " It is an isosceles triangle.
\n" ); document.write( "The fact that angles A and B have the same measure means that the sides opposite those angles (side AC and side AB) have the same measure.
\n" ); document.write( "(In any triangle, a longer side faces a larger angle, and equally long sides face equally large angles).
\n" ); document.write( "
\n" ); document.write( "\"x\"= measure of side AC (in inches) = measure of side BC (in inches)
\n" ); document.write( "\"x%2Bx%2B8=22\" because AB measures 8 inches and the perimeter is 22 inches
\n" ); document.write( "
\n" ); document.write( "Solving the equation:
\n" ); document.write( "\"x%2Bx%2B8=22\"
\n" ); document.write( "\"2x%2B8=22\"
\n" ); document.write( "\"2x=22-8\"
\n" ); document.write( "\"2x=14\"
\n" ); document.write( "\"x=14%2F2\"
\n" ); document.write( "\"highlight%28x=7%29\"
\n" ); document.write( "
\n" );
