Question

In a right triangle ABC,angle B=90degree
If AC=13cm,BC=5cm,find AB

Answer 1

$\huge\star\underline\mathfrak\green {Solution:}$

$\blue {Given,}$

Angle B = 90°

AC = 13 cm

BC = 5cm

Now,

$\pink {In\: a\:right\: -\:angle\:triangle,}$

${(Hypotenuse side)}^2= {(Perpendicular)}^2 + {(base)}^2$

$(AC)^2 = (AB)^2 + (BC)^2$

➡ ${13}^2 = ( AB)^2 + ( 5) ^2$

➡ $169 = (AB)^2 + 25$

➡ $169 - 25 = ( AB)^2$

➡ $144 = (AB)^2$

➡ $\sqrt {144}$

➡ 12 cm

$\textbf{\underline {\underline {Answer:}}}$ Side AB is 12 cm
