Answer:
≈ 8.9
Step-by-step explanation:
Assuming you are requiring the length of the unknown side
let the side ( hypotenuse ) be x
Using Pythagoras' identity
The square on the hypotenuse ie equal to the sum of the squares on the other 2 sides, that is
x² = 4² + 8² = 16 + 64 = 80 ( take square root of both sides )
x = ≈ 8.9 ( to 1 dec. place )
