hints: 

#1 angles of acute triangles are less than 90 degrees.
#2 sum of angles of a triangles always equal to 180 degrees.

sorry I was afk for awhile and I think my answer is D

rayman5766 · Answer

@Data_LG2 sorry my answer was D I was think it was d and then I had go for 15 minuets and now I am back

\int_1^e \ln\left(\sum_{k=0}^n a_kx^k\right)\,dx
