Question

Find the missing side?

Answer 1

SolutioN:-

Using Phythagoras Theorem:-

`\sf \hookrightarrow \: {(AC)}^(2) = {(AB)}^(2) +{(BC)}^(2)`

`\sf \hookrightarrow \: {(x)}^(2) = {(7)}^(2) +{(12)}^(2)`

`\sf \hookrightarrow \: {(x)}^(2) = 49 +{(12)}^(2)`

`\sf \hookrightarrow \: {(x)}^(2) = 49 +144`

`\sf \hookrightarrow \: {(x)}^(2) = 193`

`\sf \hookrightarrow \: x= √(193)`

`\sf \hookrightarrow \: x= 13.89`

Answer 2

Answer: 13.9

Work Shown:

`a^2+b^2 = c^2\\\\c = √(a^2+b^2) \\\\\text{x} = √(7^2+12^2) \\\\\text{x} = √(193) \\\\\text{x} \approx 13.892444 \\\\\text{x} \approx 13.9 \\\\`
