Question 1: SinC remains at the same point because SinC is the vertex of the triangle, it determines the height of the triangle and the length of the sides.

Question 2: In an obtuse triangle, you would always want the sides add up to more than the hypotenuse for a triangle to be able to form. In an acute triangle, the height would always need to be the smallest, like BC>AC>h. The general rule to be able to make a triangle would be AC>BC>h.
