Answer:
X ≈ 117.9°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle of interest.
Here, we have ...
X = arccos((50^2 +55^2 -90^2)/(2·50·55)) = arccos(-2575/5500)
X ≈ 117.9°
Two points on this line are (8,0) and (0,-2). The slope is thus
0-(-2)
m = ---------- = 1/4
8-0
The equation of the line is then y-0 = (1/4)(x-8), or y = (1/4)X - 2 (in slope-intercept form).

Answer:
Circular one
Step-by-step explanation:
It really depends on how you cut it, but circles are just one big edge that's curved to meet up with itself.
Also, corners aren't edges and rectangles have corners.
