please help!​

Answer 1

Answer:

41cm

Step-by-step explanation:

(hyp)²=9²+40²=81+1600=1681=41²

=>hyp=41

Answer 2

Step-by-step explanation:

The given triangle will be a right angled triangle if square of its largest side is equal to the sum of the squares on the other two sides.

According to Pythagoras Theorem,

(AC)2 = (BC)2 + (AB)2

(41)2 = (40)2 + (9)2

1681 = 1600 + 81

1681 = 1681

Hence, it is a right-angled triangle ABC.
