In a right - angled triangle , if sum of the square of the sides making right angle is 169 then what is the length of the hypotenuse ?
In a right - angled triangle , if sum of the square of the sides making right angle is 169 then what is the length of the hypotenuse ?
Explanation
According to the pythagoras theorem,
Sum of the square of the square of the sides making the right angle is equal to the square of the third side.
∴169 = square of the hypotenuse
⇒ Length of the hypotenuse =
169
=13
Hence , the correct option is 13
