Bottle, Hamburger, Ale

B+B+B=30 B+H+H=20 H+A+A=9

B=20-2H

20-2H+20-2H+20-2H=30

60-6H=30

60-30=6H

30/6=H

H=5

B=10

5+2A=9

2A=9-5

2A=4

A=4/2

A=2

intermediate Result: H=5 B=10 A=2

(H+H-B) -> inf 0 -> inf integral of (((B sin(D))/ (A D))dD

Simplifying

0 -> inf integral of B/A (sin(D)/D)dD

It is known that 0->inf of (sin(x)/x)dx is equal to π/2 Then (10/2)(π/2)

Final Result: 5π/2

Sorry for the formatting, I don’t know how to fix it
