I hope this helps. Sorry if this is wrong:( enjoy your day!!

In the Pythagorean theorem, a squared minim b squared equals c squared. If you apply that formule to question 2.

17^2-8^2 = 289 - 64 = 225 = 15^2.

Therefore, the answer to first question is yes

Then, for question 2, you do the same thing.

41^2 - 40^2 = 51

Here, 51 is not a square number. Most importantly it is not the square of9,

So this triangle is not right angled

I think if it is not correct i am vary sorry

I think its 2c and 9d. I am not completely sure but i hope this helps.
