If 10, 12 and ‘x’ are sides of an acute angled triangle, how many integer values of ‘x’ are possible?
a) 7 b) 12 c) 9 d) 13 e) 11

• 9 is the correct answer
  for acute angled triangle a^2+b^2>c^2, where c is the largest side(or one of the largest side in case of isosceles triangle)
  if c=12, then values of x satisfying above condition are: 7,8,9,10,11,12
  if c=x, then values of x satisfying given condition are: 13,14,15
  therefore there are 9 possible values of x
