Which of the following sets of numbers could not represent the three sides of a triangle?

It would be {10, 16, 27}, {12, 27, 39}, {8, 22, 31} that DO NOT represent 3 sides of a triangle

Step-by-step explanation:

Since the only answer where the first 2 numbers is greater than the 3rd/last number is {14, 28, 39} (which makes it the only traingle), the others would ALL NOT be triangles.

Options A, D

Step-by-step explanation:

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.

Step 1:  Determine if Option A is a triangle

10 + 16 = 26    <-    26 is less than 27 that means that it cannot form a triangle.

Step 2:  Determine if Option B is a triangle

14 + 28 = 42    <-    42 is greater than 39 which means that these three numbers can form a triangle.

Step 3:  Determine if Option C is a triangle

12 + 27 = 39    <-    39 is equal to 39 which means that these three numbers can form a right triangle.

Step 4:  Determine if Option D is a triangle

8 + 22 = 30    <-    30 is less than 31 meaning that these three numbers can't form a triangle.

Options A, D

the answer is c. hope this !
