10. Two angles of a triangle have measures of 45° and 75°. Which of the following could not be a measure of an exterior angle of the triangle?
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( " 60°
\n" ); document.write( " 105°
\n" ); document.write( " 135°
\n" ); document.write( " 120°
\n" ); document.write( "
\n" ); document.write( "===========
\n" ); document.write( "Find the 3rd angle.
\n" ); document.write( "Then subtract each of the 3 angles from 180 to find the exterior angles.
