What will be the length of third side of a right angled triangle whose hypotenuse is 5 cm and one of the side is 3 cm? What will be the length of third side of a right angled triangle whose hypotenuse is 5 cm and one of the side is 3 cm?

4 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the length of the 3 rd side, then

x² + 3² = 5²

x² + 9 = 25 ( subtract 9 from both sides )

x² = 16 ( take the square root of both sides )

x = = 4

The third side is 4 cm

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
