Question

For the given right triangle $ABC$, if $AC=10$ units and $BC=8$ units, then

• A. $6$ units
• B. $7$ units
• C. $8$ units

Answer 1

The correct option is A $6$ units

Given the right triangle $ABC$, with $BC=8$ units and $AC=10$ units.
Now, applying the pythagoras theorem:
$A{B}^2+B{C}^2=A{C}^2$
$\Rightarrow p^2+8^2={10}^2$
$\Rightarrow p^2=100-64=36$
$\Rightarrow p=\sqrt{36}=6$ units.
