What is the perimeter of a regular polygon with sides of length 15 cm and internal angles measuring 144° each?
Choose the correct choice from the following answers.
A) 96 cm B) 108 cm C) 120 cm D) 132 cm E) 150 cm
Sum of all interior angles is given by:   180(n-2) = n is number of sides   180(n-2) = 144*n   from here   n = 10   So perimeter becomes 15*10=
