Question

find the length of the unknown sites in the following right angled triangle x 15 CM 12 CM​

Answer 1

Answer:

9 cm

Step-by-step explanation:

here,

perpendicular=x

base=12cm

hypotenuse=15cm

by using pythagoras theorem we get,

p^2=h^2-b^2

x^2=15^2-12^2

X^2=225-144

x^2=81

x=underroot 81

X=9cm

therefore perpendicular =9cm

i hope this will help you:) if it then make me brainlist☺️

Answer 2

$\huge\frak{\colorbox{orange}{ \red{\dag \:Answer \dag}}}$

9 cm.

$\large\bold\color{tan}{\underbrace{Explanation}:-}$

We can apply Pythagoras theorem here :-

$\small \green{ {( \color{olive}{hypotenuse}})^{2} ={( \color{olive}{base}})^{2} + {( \color{olive}{height}})^{2}}$

$\small \color{blue}{here \: we \: have \: to \: find \: the \: height : - }$

$\small = > {(height)}^{2} = {(hypotenuse)}^{2} - {(base)}^{2}$

Applying all the values :-

$= > {(x)}^{2} = {(15)}^{2} - {(12)}^{2}$

$= > x^{2} = 225 - 144$

$= > x ^{2} = 81$

$= > x = \sqrt{81}$

$\large \colorbox{olive}{\color{yellow}{\fbox{= > x = 9 \: cm}}}$

Length of the unknown side in this right angled triangle is 9 cm.
