Given:
A right angle triangle with legs cm and cm. The length of the hypotenuse is x.
To find:
The value of x.
Solution:
Pythagoras theorem: In a right angle triangle,
Using the Pythagoras theorem, we get
Taking square root on both sides, we get
[Because side length is always positive]
The measure of hypotenuse is cm.
Therefore, the correct option is B.
