Answer:
Step-by-step explanation:
α + β = 180°
∠BFE and ∠FBC
∠CEF and ∠BCE
the pair of supplementary angles are
a) ∠CFB + ∠BFE = 180 and
b) ∠ BCE + ∠CEF = 180.
What is supplementary angles?
Supplementary angles are those angles that sum up to 180 degrees. We can calculate supplementary angles by subtracting the given one angle from 180 degrees.
For the given situation,
From the diagram shown the two pairs of supplementary angles are
a) [tex]\angle CFB+\angle BFE=180[/tex]
⇒ [tex]125+55=180[/tex]
b) [tex]\angle BCE+\angle CEF=180[/tex]
⇒ [tex]140+40=180[/tex]
Hence we can conclude that the pair of supplementary angles are
a) ∠CFB + ∠BFE = 180 and
b) ∠ BCE + ∠CEF = 180.
