Answer:

║JF║=75

Step-by-step explanation:

angle JDF = angle JYS ( corresponding angles)

angle JYD = angle JSF ( corresponding angles)

JD/JF=JY/JS=DY/FS

Use JD/JF=JY/JS and substitute:

50/x=42/63, where║JF║

cross multiply

50×63=42×X

3150=42x

divide via by 42

3150/42=42x/42

75=x

x=75

So ║JF║=75

Hope this helps.
