Answer :
The 120 degree angle is greater than 90 so it is obtuse. That makes the triangle obtuse by angle.
If the angles of a triangle are all different, then the sides of the triangle are different in length. That makes the triangle scalene by side.
The name of the triangle is this: obtuse scalene triangle.
