Problem:

If AE = 41, what must be the length of cord EF so that the perimeter of ∆EFS is 50?

Solution:

AE = 41

ES = AE/2

ES = 41/2

ES = 20.5

ES = AS = FS = CS = 20.5

∆EFS = 50

∆EFS = ES + FS + EF

50 = 20.5 + 20.5 + EF

EF = 50 - 20.5 - 20.5

EF = 9

Answer:

Chord EF = 9

Problem:

If CF = 50, what must be the length of chord AC so that the perimeter of ∆ACS is 60?

Solution:

CF = 50

CS = CF/2

CS = 50/2

CS = 25

CS = FS = ES = AS = 25

∆ACS = 60

∆ACS = CS + AS + AC

60 = 25 + 25 + AC

AC = 60 - 25 - 25

AC = 10

Answer:

Chord AC = 10
