Answer 1

Answer:

option 2 is correct

Answer 2

Answer:

The correct answer is option B. 5 , 7 , 13

Explanation:
We know that a triangle has three sides.

The way that we will be checking if these 3 numbers can represent a triangle is by checking if a + b ≥ c.  That means that the first two sides have to be greater than or equal to the third side.

the sum of any two vectors in magnitude must be either equal or large in magnitude must be either equal or large In magnitude of the third.

Here if we add five and seven it comes out to be 12 , which is less than 13.

Therefore the correct answer is option B .
