Finding the missing angles 35° and 145°

x = 145°

Step-by-step explanation:

Vertically opposite, also interior angles always add up to 180° so if you want to double check this, do 145° + 35° you should get 180°

I hope this helped you :)

(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

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?
