In a triangle, the value of one angle is 30 degrees, the other 60 degrees, calculate the value

In a triangle, the value of one angle is 30 degrees, the other 60 degrees, calculate the value of the third angle and write down the shape of the triangle.

From the condition of the problem, we know that the value of one angle of the triangle is 30 degrees, and the value of the second is 60 degrees. We know that the sum of all the angles of a triangle in Euclidean space is 180 degrees. Thus, to find the value of the third angle, we need to subtract the sum of two known angles from 180:

180- (30 + 60) = 180-90 = 90 degrees

Since one of the angles of the triangle has a magnitude of 90 degrees, we can say that this triangle is a right-angled triangle.
