Question

If arc CE= 40°, and m∠CDE = 30°, what is arc AB ?

A) 70°
B) 100°
C) 140°
D) 20°

Answer 1

B is the right answer
`100^(o)`

Step-by-step explanation: Hope This Helps ;)

Answer 2

Based on the given figure above, the correct answer would be option B. The measure of arc AB is 100°. If you try to analyze the image, you can say that it is 100 degrees given that arc CE is 40 degrees. By definition, one measure of an arc is the angle formed by the arc at the center of the circle that it is a part of. Hope this answer helps.
