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:
x=1/7
Step-by-step explanation:
x/2+x/5=1
make same denominators;
5x/10+2x/10=1
simplify;
7x=1
x=1/7
