Obtuse angle because is more than 90 degrees but less than 180 degrees.
IL is a diameter, which is a straight line, which is equal to 180 degrees.
The arc of IL would be 180 degrees
You are told the arc of KL is 30 degrees.
The major arc of ILK would be 180 + 30 = 210 degrees.
This should be the answer and I showed you how to do it
