Question

Find the length of the hypotenuse of a right-angled triangle whose perpendicular sides are 5, 13.

• A. $194$
• B. $13$
• C. $12$
• D. $\sqrt{194}$

Answer 1

The correct option is D $\sqrt{194}$

(Hypotenuse)${}^2$ = Sum of squares of perpendicular sides
Given, perpendicular sides are 5 and 13.
$\therefore {\text{(Hypotenuse)}}^2=5^2+(13{)}^2=25+169=194$
$\Rightarrow \text{Hypotenuse}=\sqrt{194}$
