Question

In $△ABC,\angle B$ is a right angle. If $AB=8$ and $BC=6$. find $AC$.

Answer 1

In $△ABC$ is right angle at $B$

$\therefore Base=AB=8,Altitude=BC=6$ then $Hypotenuse=AC=?$

Using Pythagoras theorem, we get

$A{C}^2=A{B}^2+B{C}^2$

$A{C}^2=8^2+6^2$

$A{C}^2=64+36$

$A{C}^2=100$

$AC=10$ unit.

This is the required answer.
