The smallest angle in a triangle is 50. Classified by angle, this is a () triangle A obtuse angle b right angle c acute angle D cannot be determined

C. (acute angle) triangle
Because there is an internal angle of 50 degrees. If it is an obtuse triangle, then one of the remaining two internal angles must be greater than 90 degrees
Assuming that the internal angle is 91 degrees, the other internal angle is 180-50-91 degrees = 39 degrees
And 39 degrees
