If the length of one leg of a right triangle is 4 and the hypotenuse is √65 , what is the length of the other leg?
Ivanshal [37]

Answer:

7

Step-by-step explanation:

Using Pythagoras' identity on 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 other leg, then

x² + 4² = (\sqrt{65} )²

x² + 16 = 65 ( subtract 16 from both sides )

x² = 49 ( take the square root of both sides )

x = \sqrt{49} = 7

That is the other leg is 7 units
