67. all 3 sides must be >0 so make each of 3 sides>0 and get 3 results. Now use the concept: sum of 2 sides> 3rd side 3 times to get 3 results. Take intersection of all the cases to get values of x (Don't forget x is natural no.)
68. x>0. use sum of 2 sides> 3rd 3 times. now
largest side can be x cm or 15 cm. use concept: for sides a,b,c for obtuse triangle a^2>b^2+c^2.
put a =15 and then a=x to get relations. Take intersection of all cases
