What is the measure of ∠CEF?
A. 80 degrees
B. 90 degrees
C. 100 degrees
D. 110 degrees
Answers
Answer:
D. 110
Step-by-step explanation:
30+40=70
180-70=110
Answer:
∠CEF = 110°
Step-by-step explanation:
ΔBED ,
∠BED + ∠BDE + ∠DBE = 180 {Angle sum property}
∠BED + 40 + 30 = 180
∠BED + 70 = 180
∠BED = 180 -70
∠BED = 110°
∠CEF = ∠BED {Vertically opposite angles}
∠CEF = 110°
