# Python: Get the third side of right angled triangle from two given sides

## Python Basic - 1: Exercise-16 with Solution

Write a Python program to get the third side of a right-angled triangle from two given sides.

Note: Use bitwise operations to add two numbers.

**Pictorial Presentation:**

**Sample Solution**:

**Python Code:**

```
def pythagoras(opposite_side,adjacent_side,hypotenuse):
if opposite_side == str("x"):
return ("Opposite = " + str(((hypotenuse**2) - (adjacent_side**2))**0.5))
elif adjacent_side == str("x"):
return ("Adjacent = " + str(((hypotenuse**2) - (opposite_side**2))**0.5))
elif hypotenuse == str("x"):
return ("Hypotenuse = " + str(((opposite_side**2) + (adjacent_side**2))**0.5))
else:
return "You know the answer!"
print(pythagoras(3,4,'x'))
print(pythagoras(3,'x',5))
print(pythagoras('x',4,5))
print(pythagoras(3,4,5))
```

Sample Output:

Hypotenuse = 5.0 Adjacent = 4.0 Opposite = 3.0 You know the answer!
