Sum = 38 + M
the sum of 5 and 38 is 43
The sum is 28+38 = 66
Let the unknown number be x: x-14+64 = 88 x = 88+14-64 x = 38 Check by substituting: 38-14+64 = 88
1, and 37 are the factors that will give you a sum of 38
38 and 12
12 and 26
38+51 = 89

171 - 38 = 133 so 133 + 38 sum to 171
Sum of interior angles of a 38 sided polygon: (38-2)*180 = 6480 degrees
20 + 18 = 38
