Answer:
18 cm
Step-by-step explanation:
The diameter of M is 76, so that means MK is 76/2 since MK is the radius
MK =38
The diameter of J is 64, so that means JL is 64/2 since JL is the radius
JL =32
JK + KL = JL
Substituting what we know (JK =12 and JL =32)
12+ KL = 32
Subtracting 12 from each side
12-12 + KL =32-12
KL =20
We want to find LM
KL + LM = KM
20 + LM = 38
Subtract 20 from each side
20-20 + LM =38-20
LM = 18
