find the no. of triangle wiith side as consequtive integers and having one of its angle equals to the twice of its another angle?

 the answer is 2.because u said that the triangle sides are consecutive.and one of the angle is twice the other.i.e.,only the pairs 1,2,3;2,3,4 are possible because on e of the sides must also be equal to twice the other

only one triangle is possible with that condition with sides 4,5,6 as sides

THE ANSWER WOULD BE THE CONSEQUTIVE PYTHOGOREAN TRIPLET LIKE 3,4,5 ........ ACTUALLY ONLY ONE IS POSSIBLE WHICH IS 3,4,5
