How many lines of symmetry does a regular polygon with x sides have

There are actually 2 variations in this case.

> First case: the number of sides is an odd number

                The number of lines of symmetry is simply equal to number of sides

> Second case: the number of sides is an even number

                The number of lines of symmetry is equal to twice the number of sides

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
