Answer:
The Second Answer , <em><u>a </u></em><em><u>pattern </u></em><em><u>of </u></em><em><u>two-dimensional </u></em><em><u>shapes </u></em><em><u>that </u></em><em><u>can </u></em><em><u>be </u></em><em><u>folded </u></em><em><u>to </u></em><em><u>form </u></em><em><u>a </u></em><em><u>solid </u></em><em><u>figure </u></em><em><u>.</u></em><em><u> </u></em>
Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
The square root of 81 is 9
Your answer is <em>9
</em>Work:
9 x 9 = 81
The answer is 150 because 30+150=180
