An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
The third angle must be 30 degrees so it is an obtuse triangle
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
Once again the answer from The WikiAnswers Community is wrong. The triangle is an obtuse angled isosceles triangle. And, as inanimate objects, triangles are not usually prone to become pregnant!
It is an obtuse scalene triangle
It is a right angle triangle providing that the 3rd angle is 30 degrees.
30
It is a right angle triangle and the 3rd angle will measure 30 degrees
The 3rd angle is 30 degrees which would form an obtuse or scalene triangle.
60 degrees. There are 180 degrees in a triangle.
It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.

If you're talking about a triangle, the third angle is 80 degrees.
