Answer:
8 Faces
Step-by-step explanation:
The Euler’s formula is:
V-E+F=2
Where V is number of vertices, E is number of edges and F is number of faces.
In our example, E=20, V=30, so we have:
30-20+F=2
10-F=2
F=8
Solve for cos(t) and sin(t):
x = 2 + 3 cos(t) ⇒ cos(t) = (x - 2)/3
y = 1 - sin(t) ⇒ sin(t) = 1 - y
Recall the Pythagorean identity,
sin²(t) + cos²(t) = 1
It follows that
((x - 2)/3)² + (1 - y)² = 1
or
(x - 2)²/9 + (y - 1)² = 1
