1) How many sides does a heptagon have?
2) What do the interior angles of a heptagon add up to?
3) What do the missing angles add up to?
4) What does each angle have to be?

the sum of the int.angles in a heptagon is (7-2)180=5*180=900

one of the angle is 144

so sum of the remaining angle si 900-144=756

as remaining angles are 6 each angle measures 756/6 degrees=126 degrees..!!!
