Answer: Second and third options are correct.
Step-by-step explanation:
As we know that
Angle at the center is the double the angle formed at the circumference of the circle.
So, An inscribed angle measure 30° if the angle formed at the circumference ( an arc measurement is of 15°)
Similarly, A central angle measures 50° with an arc measurement of 25°.
Hence, Second and third options are correct.
Answer:
The answer is the first one and the last one.
An inscribed angle measures 80° with an arc measurement of 160°.
and
An arc measures 40° with an inscribed angle is 20°.
