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
