if two base angles of an isoceles triangle are equal in measure and the third angle is five times the measure of a base angle minus 9 degrees, what are the measures of each angle.
\n" ); document.write( ":
\n" ); document.write( "Let x = measure of each of the two base angles
\n" ); document.write( ":
\n" ); document.write( "It says,\"the third angle is five times the measure of a base angle minus 9 degrees,\", therefore
\n" ); document.write( "(5x - 9) = the 3rd angle
\n" ); document.write( ":
\n" ); document.write( "The three angles = 180
\n" ); document.write( "x + x + (5x - 9) = 180
\n" ); document.write( "2x + 5x = 180 + 9
\n" ); document.write( "7x = 189
\n" ); document.write( "x = \"189%2F7\"
\n" ); document.write( "x = 27 degrees, the two base angles
\n" ); document.write( "and
\n" ); document.write( "5(27) - 9 = 126 degrees, the third angle
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check: 27 + 27 + 126 = 180 \n" ); document.write( "
\n" );
