Answer 1

B.

Explanation:
`6\sqrt{3`

Answer 2

Option 2 is correct.

Explanation:

See the given figure.

Here triangle MTU is a right triangle.

Hence, applying Pythagoras theorem,

TU² = TM² - MU² = 6² - 3² = 27 ....... (1)

Now, triangle NTU is also a right triangle.

Hence, NT² = TU² + NU² = 27 + 9² = 108

So, NT = √108 = 6√3

Therefore, option 2 is correct. (Answer)
