Answer 1

$\orange{I~took~it~as~a}$

$\bold\green{Right~Angle~Triangle}$

$\blue{As~u~just~mentioned~it~as~a~∆}$

$\large\underline\mathrm\red{Given}$

$\orange{In~∆PQR}$

$\blue{PR~=3~cm}$

$\blue{QR~=2~cm}$

$\large\underline\mathrm\red{To~find}$

$\blue{PQ~}$

$\orange{Which~is~the~Hypotenuse}$

$\large\underline\mathrm\red{Theorem}$

$\orange{Pythagoras~Theorem}$

$\blue{In~a~Right~Angle~∆,~PRQ~where~∠R=90°}$

$\blue{PR²~+QR²~=PQ²}$

$\orange{⇨}$$\blue{side1²~+side2²~=hypotenuse}$

$\large\underline\mathrm\red{Calculation}$

$\orange{According~to~the~theorem}$

$\orange{⇒}$$\blue{3²~+2²~=PQ²}$

$\orange{⇒}$$\blue{9~+4~=PQ²}$

$\orange{⇒}$$\blue{13~=PQ²}$

$\orange{⇒}$$\blue{√13~=PQ}$

$\orange{⇒}$$\blue{3.606=PQ}$

$\large\underline\mathrm\red{Solution}$

$\orange{PQ~=}$$\green{3.606}$$\blue{(near~value)}$
