Answer:

middle option

Step-by-step explanation:

It is commonly practiced, in the absence of any other definitions that would state otherwise, that angles measured in a anti-clockwise sense are considered positive angles.

In your question, only the middle option measures the angle in an anti-clockwise manner and hence the middle option is said to have a positive angle.

The only angle with a positive measure is the middle one.

When an angle has a positive measure?

In standard notation, an angle has a positive measure when it is measured counterclockwise.

Where counterclockwise means that the arrow goes left-wise in a circular motion.

On the other hand, when the angle is measured clockwise, the measure will be negative.

With this in mind, the only angle that is measured counterclockwise is the middle one, so that is the only angle with a positive measure.
