The total of the 8 angles for an octagon is (n - 2) * 180 degrees = 1080 degrees.
1080- 845 = 235 degrees.
x + y + z = 235
235 = 180 = 55 degrees, this one of the angles.
90 degrees - 55 degrees = 35 degrees, this another angle.
180 degrees -35 degrees = 145 degrees, this is the third angle.
Cleomenius.
55 + 35 + 145 + 845 = 1085.
This does check.
