Answer:B
Step-by-step explanation:
Call this triangle ABC, with A at the top vertex, B at the right angle, and C at the last vertex.
Tan (A)= 6/10 = 3/5
B is not acute
Tan (C)= 8/6= 4/3
Tan^-1 ( 3/5) =30.96375653...
Tan ^ -1 ( 4/3) =53.13010235...
Thus, tan(B) is the smallest.
Looking at the answer choices, it is B.
