Answer:

Step-by-step explanation:
We want to find the indefinite integral

We can rewrite this in the form: 
This will allow us to use tables of integration.
We use formula 31 from the table of integration shown in the attachment.

We let
,then

We simplify to get:

If we continue the line which comes from line segment I till we reach line n then the angle formed will be 31 degrees ( interior alternate to 31 degrees)
x + 31 = 62 ( external angle of a triangle theorem).
Therfore x = 31 degrees answer
