Answer 2

Answer:

• Q11 - 12 sides
• Q12 - 10 sides

Step-by-step explanation:

Use the formula for sum of interior angles of a regular polygon:

• S = 180(n - 2)

Each angle A measures:

• S/n = 180(n - 2)/n
• A = 180(n - 2)n
• An = 180n - 360
• (180 - A)n = 360
• n = 360/(180 - A)

Question 11

Each angle is 150, then finding n:

• n = 360/(180 - 150)
• n = 360/30
• n = 12

Question 12

Each angle is 144, find n:

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