Answer: Scalene triangle 
Step-by-step explanation:
All triangles have three sides with specific lengths and angles, but a scalene triangle is a kind of triangle that has each of its three sides to be of different lengths and angles. 
Hence, a triangle that measures 39°, 104°, and 37° definitely has three sides with different lengths and angles. 
Thus, it is a scalene triangle.

Answer:
1/4
Step-by-step explanation:
total balls=7+4+4+5=20
 probability of green marble=?
green marbles are 5 so,
        Probability=number of favourable outcomes / number of all possible outcomes
