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>
<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
