I think the answer is: each shelf is 76 inches, if you take 76x5 it comes out to 380 so that would leave the 20 inches left over, hope that makes sense

THE 5 IDENTICAL SHELVES WOULD  have to be 76 because if you take 400 - 20 (because that left over) you get 380/5 you get 76 and to check your work you do 5x76=380+20 you get 400 so 76 is you answer

Answer:

option 3- 5 square root 2

Step-by-step explanation:

\sin 45° = \frac{BY}{OY} \\  \\  \frac{1}{ \sqrt{2} }  =  \frac{BY}{10}  \\  \\ BY =  \frac{10}{ \sqrt{2} }  \\  \\ BY =  \frac{10 \times  \sqrt{2} }{ \sqrt{2} \times  \sqrt{2}  }   \\  \\ BY =  \frac{10 \sqrt{2} }{2 }   \\  \\  \huge \red{ \boxed{BY =  5 \sqrt{2} }}
