Question

Find the length of the hypotenuse in a right angled triangle if the sum of the squares of the sides making right angle is 169.

• A. $15$
• B. $13$
• C. $5$
• D. $12$

Answer 1

Answer: (B)

$13$

According to the Pythagoras theorem, the sum of the squares of the sides making the right angle is equal to the square of the third side (hypotenuse).

$\therefore$ Square of the hypotenuse $=169$

$\Rightarrow$ Hypotenuse $=\sqrt{169}$

$=13units$

Hence, option B is correct.
