Explanation:

Step1: Identify tangent segments from J

Tangents from J to circle: JK and JI, so JK = JI.

Step2: Identify tangent segments from L

Tangents from L to circle: LK and LM, so LK = LM = 9.

Step3: Calculate JK

JK = JL - LK = 28 - 9 = 19.

Step4: Identify tangent segments from P

Tangents from P to circle: PO and PI, so PO = PI.

Step5: Identify tangent segments from N

Tangents from N to circle: NO and NM, so NO = NM = 17.

Step6: Calculate PO

PO = PN - NO = 28 - 17 = 11.

Step7: Calculate IJ

IJ = JI + PI = JK + PO = 19 + 11 = 26.

Answer:

26
