Answer:

triangle isn't right angled

Explanation:

For a right tangled triangle :

Length of the longest side, hypotenus is given by :

Hypotenus = √(opposite² + adjacent ²)

From.the question :

Hypotenus = 11

Opposite and adjacent = 5 units and 6 units

Let's test :

Hypotenus = √(5² + 6²)

Hypotenus = √(25 + 36)

Hypotenus = √61 units

Hypotenus = 7.8

Hypotenus for a right angled triangle = 7. 8 units and not 11.

Hence, triangle isn't right angled
