No. You were correct the first time. An octagon has 8 sides. A regular polygon means that all sides are congruent, and all angles are congruent. Since it has 8 sides of the same length, and the perimeter is 72 cm, then you can divide (72 cm)/8 = 9 cm, so you get that each side is 9 cm long. If you were not told it is a regular octagon, you wouldn't be able to answer the question because the sides would have different lengths.

The sum of the measures of the angles of a triangle is 180 degrees. All three angles must add to 180. You were given the measures of two angles. Add them up. Then subtract the sum from 180, and that is the measure of the third angle.

97

Great. 62 + 35 = 97 Now subtract the sum 97, from 180. What is 180 - 97 = ?
anonymous

83

  • mathstudent55
Correct. To double check, just add: Is 62 + 35 + 83 = 180? Yes, it is, so 83 is correct.
