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°.

Answer 1

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

Answer 2

Answer: Second and third options are correct.

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.
