A:
Answer:A regular polygon first maps directly onto itself after rotating 20 degrees has 18 sides Explanation: Given: Angle rotated=20 degrees To find: Number of sides the polygon has=? Solution: [tex]\text { The number of sides the polygon have }=\frac{\text { total angle }}{\text { angle rotated }}[/tex][tex]\text { We know that the total angle of polygon }=360^{\circ}[/tex] [tex]\text { The number of sides the polygon have }=\frac{360^{\circ}}{20^{\circ}}[/tex] [tex]\text { The number of sides the polygon have }=18\\[/tex]RESULT:Hence the number of sides the polygon has =18
