D. 245

Answer 1

------------------------------------------------------------
Formula
------------------------------------------------------------
Sum of all interior angles of a polygon = (n-2) x180
where n is the number of sides

------------------------------------------------------------
Sum of all interior angles of an octagon
------------------------------------------------------------
(8 - 2) x 180 = 1080°

------------------------------------------------------------
Find the 8th angle
------------------------------------------------------------
1080 - 835 = 245°


------------------------------------------------------------
Answer: The 8th angle is 245° (Answer D)
