Thanks for this question. Your question was: The given triangle is a right angled triangle. You have to find out the length of the third side which is unknown i.e. side LN.
Your Correct answer: e
Now I'm trying to Explain to you how?
Since, the given triangle is a right angled triangle we have the standard formula to find the length of the hypotenuse. This formula is stated as follows,
(Hypotenuse)2 = (one side)2 + (other side)2
i.e. (LN)2 = (LM)2 + (MN)2
∴ (LN)2 = (144) + (225)
∴ (LN)2 = 369
Now, taking square roots on both sides of the equation, we get,
LN = 19.2093
But, none of the options represents this value.
Hence, the correct answer is option e.
