<span>Given that RS = 6, ST = 3, and SL = 4, to find NS, we first find QS.
Notice that NQS forms a right triangle with the right andle at Q.
To find QS, we notice that QRS forms a right triangle with the right angle at R.
Note that ST = QR = 3 and RS = 6.
Using pythagoras theorem
Note that NQ = SL = 4.
