Have you made any attempt to answer this question? You must show some work before we can help you. Also, in future, would you please write in lower case: upper case is considered to be shouting.

 

[ICEMANN6859]

Yes I have, but I'm not getting the same answer as in the book.
Sorry about the upper caps.

 

[ICEMANN6859]

35kg*9.8= 343N
343N cos 15 degrees = .97
