Answer:
B
Step-by-step explanation:
The central angle ANC is equal to the arc ABC that subtends it, thus
arc ABC = 138° → B
Answer:its correct i believe
Step-by-step explanation:
Answer:
X×W
Step-by-step explanation:
Product multiplies, whereas addition increases value steadily. Subtraction reduces a value, hence X×W has the greatest value.
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°
If a pair of alternate exterior angles are supplementary, what is the measure of each angle? it should be 180 if im not mistaken
