Aregular polygon has possible angles or rotational summetry of 20, 40, and 80 degrees. how many side does the polygon have?

The number of sides regular polygon have = 18

Step-by-step explanation:

The possible angle or rotational symmetry is 20° , 40° , 80° of any regular polygon .

now,

Symmetrical under 20° Rotation is also symmetrical on rotation of any multiple of 20°

So, number of sides = n =

I.e                                  n =  

So,                                 n = 18

Hence the number of sides the polygon have 18    Answer  

answer: group b.

step-by-step explanation:

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
