(d) 11, 60, 61​

Answer 1

Answer:

Hey mate this could be founded by using Pythagoras theorem or Pythagorean triplet.

Step-by-step explanation:

Answer is option A. 5,12,13

Answer 2

Answer:

c)9,40,42

Step-by-step explanation:

According to Pythagoras theorem:

S^2+S^2 = H^2.

=> 9^2+40^2

= 81+1600

= 1681

=41^2.

=>42^2 not equal to 41^2.

Therefore the given triplet does not follow the Pythagoras theorem.

Therefore it does not forms a right angled triangle.
