Answer:
6 foot
Explanation:
The Length of the blacktip shark = 8 foot
The blacktip shark and a spinner shark = 14 foot hammerhead shark
That is,
Length of the blacktip shark + Length of the spinner shark = 14 foot
8 + Length of the spinner shark = 14 foot
Length of the spinner shark = 14 -8 foot = 6 foot
