If the measure of arc KM is 112°, find the measure of arc LM

The answer is 124
All circles are equal to 380 degrees
You’re alr told that a part of the circle is equal to 112
So you subtract 360-112 which is 248
This means that the rest of the circle (without the zone that KM covers) is 248
As you can see both sides (ML and KL) are equal because they have congruency lines
So both sides have the exact same length
If what’s remaining is 248 and there are 2 equal sides you just have to divide
248/2 and that is 124
