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°.

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.

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°.

the guy above is wrong do not do his answers
