Answer:
81°+x=180°[co interior angles]
x=180°-81°
x=99°
x°=(3y+33)°
99°=(3y+33)°
99-33=3y
66=3y
66/3=y
22=y
To get the area you need to multiply so you would multiply 123° and 18.6 and you would get =2287.8
Answer:
We can now prove Euler's formula (v − e + f = 2) works in general, for any connected simple planar graph. Proof: by induction on the number of edges in the graph. Base: If e = 0, the graph consists of a single vertex with a single region surrounding it. So we have 1 − 0 + 1 = 2 which is clearly right.
