The third angle must be 60 degrees so it is a scalene triangle
As the third angle must be 42 degrees, it is a scalene triangle.
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.

All triangle angles add to 180 degrees. Since one is 38 and the right angle is 90, the third angle is 180 -38-90 = 52 degrees
One in which the third angle is 180o - (48o + 68o) = 64o and as all three angles are different, it is a scalene triangle.
I believe a scalene triangle CAN have a right angle. Def of scalene tri: a triangle with no equal sides, and no equal angles. A triangle with angles of 90, 29, and 61. Sides of 15.0, 27.0, and 30.9 this satisfies the definition. If you look at it the other way: can a right triangle be non-scalene, and there is only one possibility: the isosceles right triangle (45°, 45°, 90°), with sides (square_root(2), 1, and 1). It's not possible for an equilateral triangle to have a right angle. So all other right triangles are scalene (but not all scalene triangles are right triangles).
The third angle is (128 degrees) minus (the second angle).
