The 3rd angle in an isosoles triangle is 8 degrees less than twice the measure of the equal angle. Find the measure of one of the equal angle.
\n" ); document.write( ":
\n" ); document.write( "Let x = the measure of one of the equal angles
\n" ); document.write( ":
\n" ); document.write( "It says,\"The 3rd angle is 8 degrees less than twice the measure of the equal angle.\" therefore
\n" ); document.write( "(2x - 8) = 3rd angle
\n" ); document.write( ":
\n" ); document.write( "The three angles = 180
\n" ); document.write( "x + x + (2x-8) = 180
\n" ); document.write( ":
\n" ); document.write( "4x - 8 = 180
\n" ); document.write( ":
\n" ); document.write( "4x = 180 + 8
\n" ); document.write( ":
\n" ); document.write( "x = 188/4
\n" ); document.write( ":
\n" ); document.write( "x = 47 degrees is the measure of one of the equal angles
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution, 3rd angle = 2(47) - 8 = 86 degrees:
\n" ); document.write( "47 + 47 + 86 = 180
\n" ); document.write( " \n" ); document.write( "

\n" );
