The answer is the last one
The interior angle of a regular polygon is equal to each other since all sides of the polygon are congruent. The formula that expresses the relation of the sides of the polygon and the measurement of the interior angle is (n2)*180/n where n is 7. Each interior angle then measures 128.6 degrees.
Yes, it is the longest river
D. works because if you work it out that means 2n=140 and then divide by 2 which means n=70 and the other number is 71
Since its largest to smallest, start with the bigger numbers! your answer will be
779,500 545,417 459,300 293,000 273,481
