1) A polygon has n sides. If one of its interior angles is 84 deg, and the other interior angles are each equal to 156 deg, find n.

2a) If a product of two positive integers is a prime number, what must be the value of the smaller integer?
2b) Given that x and y are positive integers, solve x^squared - y^squared = 13

3) Given that 950k is a perfect cube, find the smallest possible value of k.


Please include workings. Very grateful for your help.

1)  84 + 156(n-1) = 180(n-2)
n = 12

2a) 1

2b) 7^2 - 6^2 = 13

3) 950 =  2  x 5 x 5 x 19
K = 2 x 2 x 5 x 19 x 19 = 7220
