The measure of ∠ B is 68 °. What is the measure of its supplementary angle?
A)22°
B)90°
C)112°
D)180°

112 degrees

Step-by-step explanation:

supplementary angles equal to 180 degrees so therefor if you subtract 68 from  180 you will get 112

(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
