Answer :-

  • The hypotenuse of the right angled triangle is 15 cm.

To find :-

  • The length of the hypotenuse of a right angled triangle whose remaining sides are 9 cm and 12 cm.

Step-by-step explanation :-

  • Here, the other two sides of a right angled triangle are given to us. We have to find the length of it's hypotenuse.

We know that :-

  • In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Here,

  • The other two sides are 6 cm and 12 cm.

Therefore,

\longmapsto\sf Hypotenuse^2 = 9^2 + 12^2

\sf \longmapsto Hypotenuse^2 = 81 + 144

\sf \longmapsto Hypotenuse^2 = 225

\sf \longmapsto Hypotenuse = \sqrt{225}

\longmapsto \underline{\boxed{\sf Hypotenuse = 15 \: cm}}

--------------------------------------------

  • Hence, the hypotenuse of the right angled triangle is 15 cm.

 \huge \maltese  \sf \: {given}

 \bold{ \dagger \: base \: and \: perpendicular = 9  \: cm \: \: and \: 12 \: cm}

 \huge \sf \underbrace \color{blue}{formulae}

 \bold{ \leadsto \: ( {hypotenuse})^{2}  =  ({base})^{2} +  ({perpendicular})^{2}}

 \sf \hookrightarrow \:  {(hypotenuse)}^{2}  =  {9}^{2}  +  {12}^{2}

 \sf \hookrightarrow \:  {(hypotenuse)}^{2}  = 81 + 144 = 225

  \sf\hookrightarrow \: hypotenuse =  \sqrt{225}

 \underline \bold{ \longmapsto \: hypotense = 15}
