Answer:

  • Q11 - 12 sides
  • Q12 - 10 sides

Step-by-step explanation:

<u>Use the formula for sum of interior angles of a regular polygon:</u>

  • S = 180(n - 2)

<u>Each angle A measures:</u>

  • S/n = 180(n - 2)/n
  • A = 180(n - 2)n
  • An = 180n - 360
  • (180 - A)n = 360
  • n = 360/(180 - A)
<h3>Question 11</h3>

<u>Each angle is 150, then finding n:</u>

  • n = 360/(180 - 150)
  • n = 360/30
  • n = 12
<h3>Question 12</h3>

<u>Each angle is 144, find n:</u>

  • n = 360/(180 - 144)
  • n = 360/36
  • n = 10
