360-(55+60+63+70+81)=6th exterior angle
360-329=6th exterior angle
31=6th exterior angle
all exterior angles of any polygon has a measure of 360

First: Subtract one hundred thirty° from a hundred and eighty° and upload that distinction by capacity of fifty 5° and sixty 5°. the total perspective of triangle is a hundred and seventy°, no longer a hundred and eighty°; for this reason, one hundred thirty° will no longer be able to be outdoors perspective diploma. 2d: stick to same technique for looking the interior angles. (a hundred and eighty-a hundred and fifteen)°+(a hundred and eighty-a hundred and twenty)°+(a hundred and eighty-one hundred twenty five)° = sixty 5°+60°+fifty 5° = a hundred and eighty°
