Answer:
132 degrees.
Step-by-step explanation:
Since the lines are parallel, the opposite angle is always the same, and since 48 degrees was the smaller bottom angle, the upper smaller angle is also 48 degrees. The line's total angle is 360 degrees, so 48 + 48 is 96, and 360 - 96 is 264, and then 264 divided by 2 is 132, so the larger angles on both intersections are 132 degrees.

Step-by-step explanation:
In this case, i woudnt reccomend to use integration by parts, becuase you are not simplifying the expression by doing an integration and a derivation. It is not easy to integrate 1/x³+1, and if you derivate it, then a natural logarithm would appear, and the integral wont be easier after this parts step.
It is a better idea to use integration by substitution. Note that if you replace x³+1 by a variable y, we have that dy = 3x² dx. We can easily make a 3xdx appear in the integral by multiplying and dividing by 3, solving the integral easily:

(Note that, if x ranges from 0 to 1, then u = x³+1 ranges from 0³+1 = 1 to 1³+1 = 2)
