Choose all that are correct. An inscribed angle measures 80° with an arc measurement of 160°. An inscribed angle measures 30° with an arc measurement of 15°. A central angle measures 50° with an arc measurement of 25°.An arc measures 40° with an inscribed angle is 20°.
Accepted Solution
A:
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.
