The lengths of the sides of a triangular garden are 10m, 11m, and 13m. find the measure of the angle opposite the longest side to then nearest tenth of a degree

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

u bout ugly as   a mf
