Answer:

C

Explanation:

Using Pythagoras' identity to determine if the triangle is right

The square of the longest side should equal the sum of the squares on the other 2 sides, that is

QS² = RS² + QR² = 8² + 5² = 64 + 25 = 89 ( take the square root of both sides )

QS =
√(89)

Δ QRS is not right as QS would have to be
√(89)
