a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.

yes all scalene triangles are actue. All the angles are 60 degrees. :)
yes as long as neither of the other angles are 45 degrees it can be scalene but it can not possibly be equilateral
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
Yes, normally it is but it can also be an isosceles triangle if it has an obtuse angle and 2 equal acute angles.
The definition of an obtuse triangle is a triangle with an angle exceeding 90o. A scalene triangle is a triangle in which no two sides are of equal length. Therefore, it is possible that an obtuse triangle is a scalene triangle. However, it is also possible for an obtuse triangle to be an isosceles, in which two sides are of equal length. On a final note, it is impossible for an obtuse triangle to be an equilateral; equilateral triangles always have angles of 60o.

its a triangle has 1 obtuse angle greater than 90 degress it also scalene NO equal sides
does a equilateral triangle have 2 interior angles
Since the sum of the angles of a triangle = 180c, then the third angle is 15 degrees, Since the three angles are all different in size 140,25, & 15, this makes the three sides of different lengths. Since the three angles are all different then it is a scalene triangles, also one angle is greater than 90 degrees , at 140 degrees. This makes the angle obtuse. So overall the triangle is an obtuse scalene triangle.
Obtuse triangles can also be scalene if none of the sides are of equal length. Otherwise, it is an isosceles triangle.
If the triangle has an obtuse angle then the other two angles must sum to less than 900. The triangle therefore CANNOT be an equilateral triangle. It CAN be an isosceles triangle with the two equal angles summing to less then 900. For Example, 1200, 300, 300. It could also be a scalene triangle with angles such as 1200, 500, 100.
