The total number of degrees in an octagon is 180(n-2) = 180(8-2) = 1080 degrees.
The four angles you were given add to 595 degrees.
Thus there are 1080 - 595 = 485 degrees to be spread evenly among the four remaining angles...
485 / 4 = 121.25 degrees each

135*8 = 1080 total degrees in an octagon
1080-595= 485
485/4 = 121.25
