To solve this problem you must apply the proccedure shown below:
 By definition, Cosine is:
 Cos(angle)=adjacent side/hypotenuse
 Therefore, you have:
 Cos(B)=32/40
 By simplifying, you obtain that:
 Cos(B)=4/5

cos b = adjacent/ hypotenuse 
adjacent = 32 
hypotenuse = 40

cos b = 32 / 40

cos b = 4 /5

The answer is option 1
