That depends on the type of triangle it is but in general the 3 interior angles of any triangle add up to 180 degrees.
An obtuse triangle is a triangle that has one angle greater than 90 degrees.
A triangle with one angle over 90 degrees is an obtuse triangle.
right triangle
40 degrees
A right-angle triangle will have one right-angle (90 degrees).

A Right Triangle is a triangle that has one corner with a 90-degree angle. So a Right Angle is an angle of 90 Degrees or also known as Perpendicular angle.
It has 180 degrees, but one angle of the triangle has to be 90 degrees

40 degrees
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
An obtuse angled triangle.
