.

Step-by-step explanation:

We know that a central angle is equal to its subtended arc.

In this case, the subtended arc is 135°, that means the central angle KOL is equal to 135°.

Then, we transform from degrees to radians. We know that is equivalent to 180°, so we use the rule of three.

Using , we have

Therefore, the radian measure of the central angle is .
