Question
Some question and their alternative answer are given.
In a right-angled triangle, if sum of the squares of the sides making right angle is 169 then what is the length of the hypotenuse?
Options
15
13
5
12
Solution
13
Explanation:
According to the Pythagoras theorem,
Sum of the squares 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 = `sqrt169` = 13
Hence, the correct option is 13.
