FIRST PART:
Let the angle be x%5Eo.
Then, its supplement = %28180+-+x%29%5Eo
Its complement = %2890+-+x%29%5Eo; twice the complement = 2%2A%2890+-+x%29%5Eo
By problem,
%28180+-+x%29+-+2%2A%2890+-+x%29+=+10
or 180+-+x+-+180+%2B+2x%29+=+10
or x = 10

Ans: The reqd. angle is 10 degrees.


SECOND PART:
Let the numbers be (n-2), (n-1), n, (n+1) and (n+2).
Their sum = (n-2) + (n-1) + n + (n+1) + (n+2) = 5n = 0 (given)
So n = 0.

Ans: The integers are -2, -1, 0, 1 and 2.
