Answer:
third side = 6
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 the third side be x , then
x² + 4² = (2
)²
x² + 16 = 52 ( subtract 16 from both sides )
x² = 36 ( take square root of both sides )
x =
= 6
