The internal angles in a "Scalene" triangle are all different.
The 120 deg angle is "Obtuse", not the triangle.
The 15 deg angle is "Acute", not the triangle.
That would be on Jeopardy:
What is a "Scalene"

It is an obtuse triangle based on the definition of an obtuse triangle*an obtuse triangle is one that has an obtuse angle(an angle which is morethan 90 degrees but less than 180 degrees), which means that the other two triangles are acute, being each is less than 90 degrees). The given triangle satisfies the definition of an obtuse triangle.
Furthermore, based on the given angles which are all unequal, we can also say that it is an scalene triangle since the sides opposite these unequal angles are also unequal---the very definition of an scalene triangle.

A scalene triangle. Or it could be an obtuse triangle.
In a scalene triangle all sides have different lengths. The internal angles in a scalene triangle are all different.
An obtuse triangle has one internal angle larger than 90°

The triangle is a spherical triangle. In spherical triangle the angles are the angle between the tangents drawn at the point of intersection of the circles drawn on a sphere. The triangle formed by intersection of three circles. In spherical triangle the sum of the three angles need not be equal to 180°. This kind of spherical trigonometry is used in Astronomy.

it is definetly an obtuse triangle. an obtuse triangle has one angle measureing more than 90 degrees. it is acute when it has all angles less than 90 degrees and it is a right triangle when it has 1 angle that is 90 degrees.

well u can call it an obtuse angle triangle .as none of it's angles are same it is a scalene triangle.hence it is a scalene obtuse triangle.

ok so the angles of a triangle upload as much as a hundred and eighty, such as you pronounced, so 3y + 2y + 40 5 = a hundred and eighty And it extremely is now purely an elementary equation the place you will possibly desire to discover the variable: 3y + 2y = a hundred and eighty - 40 5 5y = a hundred thirty five y = a hundred thirty five/5 y = 27 elementary! :)

Obtuse...because one angle is over 90 degrees.
Scalene...if the sides are also different lengths.

it is obtuse as one angle is > 90 degrees
