Answer 1

Using diagram from your another question .

• AB=4
• BC=10

Use Pythagorean theorem

`\\ \rm\longmapsto AC^2=4^2+10^2=16+100=116`

`\\ \rm\longmapsto AC=10.77`

• cos20=0.94

• BC/AC=10/10.77=0.91

Not satisfied (Close but we can't ignore 0.03)

Let required BC be x

`\\ \rm\longmapsto (x)/(10.77)=cos20`

`\\ \rm\longmapsto x=0.94(10.77)=10.124ft`

Camera should be shifted 0.124ft left
