plz give the question full answer explaination​

Answer 1

1) according to pythagoras theorem

$( {ac}^{2} ) = ( {bc}^{2}) + ( {ab}^{2})$

[

$({41}^{2} ) = ( {40}^{2}) + ( {9}^{2})$

[

$1681 = 1600 + 81$

$</p><p>1681 = 1681$

it is right angled triangle ABc

I think it will be like this, comment if you feel right
