The sum of the interior angles of a hexagon is equal to sum of six consecutive numbers. Hence let the smallest consecutive number be x. Then other five numbers are x+1, x+2, x+3,x+4 and x+5. Hence the measure of the smallest angle is 117.5 cm.
The range is the difference between the LOWEST value and the HIGHEST value. The range is the set of POSSIBLE output values, and that is shown on the Y-AXIS!!
