Answer:

Step-by-step explanation:
The given line passes through (0,8) and (8,0).
The slope of this line is
.
The point-slope form is given by:

We substitute the slope and the point (8,0) to get:

We substitute the slope and the point (0,8) to get:

Well according to my calculations the image isn't exactly correct, but:
n(unknownangle) = 180 - 125 = 55
360 = 120 + 55 + 90 + x
x = 95
180 - 95 = 85
------------------
x = 95
y = 85
