Question

Find the missing side?

Answer 1

SolutioN:-

Using Phythagoras Theorem:-

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

`\sf \hookrightarrow \: {(x)}^(2) = {(11)}^(2) +{(15)}^(2)`

`\sf \hookrightarrow \: {(x)}^(2) = 121 +{(15)}^(2)`

`\sf \hookrightarrow \: {(x)}^(2) = 121 +225`

`\sf \hookrightarrow \: {(x)}^(2) = 346`

`\sf \hookrightarrow \: x= √(346)`

`\sf \hookrightarrow \: x= 18.6`
