题目是用英文写的,
Each exterior angle of a regular polygon of n sides is 16 degree greater than each exterior angle of another regular polygon of 3n sides.
(a) Form an equation in n and solve for the value of n
(b) Calculate the interior angle of the regular polygon of 3n sides

正n边形的每个外角比正3n边形的每个外角大16°,(a)求n满足的方程并解出n(b)计算正3n边形的内角.
n多边形的外角和:360°,所以正n边形的每个外角:360°/n,正3n边形的每个外角:120°/n于是有
360°/n=120°/n+16°,也即:16n=240,解得n=15
正45边形的外角为:8°,所以内角为172°
n=15,the interior angle of the regular polygon of 3n sides=172度
