Due Tomorrow: Answer question 18 using steps

Answer 1

`\\ \sf\longmapsto tan51=(BC)/(AB)`

`\\ \sf\longmapsto 1.23=(9)/(AB)`

`\\ \sf\longmapsto AB=(9)/(1.23)`

`\\ \sf\longmapsto AB=7.3\approx 7in`

Now

`\\ \sf\longmapsto AC^2=7^2+9^2`

`\\ \sf\longmapsto AC^2=49+81`

`\\ \sf\longmapsto AC^2=130`

`\\ \sf\longmapsto AC^2\approx 11in`
