180 degrees because the 4 interior angles of a quadrilateral add up to 360 degrees and the 3 interior angles of a triangle add up to 180 degrees
If you mean an equilateral triangle then the 3rd angle is 60 degrees
An obtuse triangle

No, a triangle has three sides, a quadrilateral has four.
Any triangle with a 90 degree angle is classified as a right triangle.
360
It is a right angle triangle and the 3rd angle will measure 30 degrees
The obtuse angle is greater than 90 and less than 180.
Obtuse triangle
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
Any triangle that has an angle measuring 90 degrees is a right triangle.
