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.

My questions given answers are below. I need to choose correct answer. But I don’t know which one is correct. Please help.

a. 12

b. 15

c. 37

d. 14

e. None of the above

Thanks.

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.
