Question

6. Arc AB measures 80' which is an intercepted arc of a central angle AOB, what is the measure of angle AOB? A. 40° B. 80° C. 160° D. 260° Too complex/wrong grammar= 1 star Correct answer/quick solution= 5 star

Answer 1

NOTE: we will assume that 80' represents 80°.

If an arc of a circle measures 80°, its central angle will also measure 80°.

We can see it in a graph as:

NOTE: The length of the arc will depend on the radius of the circle.

Answer: B. 80°
