There is a mirror in the shape of a regular triangle with a side length of 50 centimeters (cm). If you want to place the lights around the perimeter of this mirror with 10 centimeters (cm) of intervals, how many lights do you need?
50 3 [OP_MUL] 10 [OP_FDIV]
var_a = 50
var_b = 3
var_c = var_a * var_b
var_d = 10
var_e = var_c // var_d
print(int(var_e))
