Question

find the length of the hypotenuseof a right angle triangle whose other sides are 12 cm and 5 cm​

Answer 1

Answer:

13 cm

Step-by-step explanation:

If the length of hypotenuse = x

12² + 5² = x²

144 + 25 = x²

√169 = x

13 cm = x

Answer 2

Step-by-step explanation:

${\Huge{\underline{\underline{\bf{\maltese Question:-}}}}}$

:$\Rightarrow$ $\mathrm{find\ the\ length\ of\ the\ hypotenuse\ of\ a\ right\ angle\ triangle\ whose\ other\ sides\ are\ 12\ cm\ and\ 5\ cm.}$

${\Huge{\underline{\underline{\bf{\maltese Answer:-}}}}}$

:$\Rightarrow$ $\mathrm{By\ pythagoras\ theorem,}$

:$\Rightarrow$ $\mathrm{AC²\ =\ AB²\ +\ BC²}$

:$\Rightarrow$ $\mathrm{AC²\ =\ (12)²\ +\ (5)²}$

:$\Rightarrow$ $\mathrm{AC²\ =\ 144\ +\ 25}$

:$\Rightarrow$ $\mathrm{AC²\ =\ \sqrt{169}}$

:$\Rightarrow$ $\mathrm\purple{AC²\ =\ 13cm}$

:$\Rightarrow$ $\mathrm{So,\ the\ length\ of\ the\ hypotenuse\ of\ a\ right\ angle\ triangle\ is\ 13cm.}$
