Sam has 32 books in his library. He bought Several books at a yard sale over the weekend. He now has 92 books in his library. How many books did he buy at the yard sale?

What i would do is subtract 92-32= 60  and see if that is my answer.

so I think he bought 60 books at the yard sale.

Step-by-step explanation:

should be sixty yeah

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
