Web17 jan. 2024 · Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees. How many diagonals does a 15 gon have? Therefore, there are 90 diagonals in a 15 sided polygon. How many lines of symmetry does a regular 18 gon have? degree rotational symmetries. Web7 sep. 2024 · In fact, each person shakes hands with 99 others, so there should be 100*99 = 9900 handshakes; but again, it takes two people to shake hands, so this is double the correct amount, which is 4950 handshakes. By now the pattern should be clear. If there are n people at a party, the number of handshakes is n (n-1)/2.

Web5 dec. 2024 · How many sides does it have is 36 sides. The regular polygon of n sides is: . a=(n-2)×180/2. Solve for n. 160=(n-2)×180/n. Multiply both sides by n. 170n=(n-2)×180. Simplify. 170n=180n-360. Subtract from both sides. 0=10n-360. Divide both sides by 10. n=360/10. n=36. Inconclusion How many sides does it have is 36 sides..
