Question

Which of the following sets of numbers could represent the three sides

of a triangle?
O {6, 20, 28}
O {4, 11, 15}
O {9, 19, 30}
O {5, 15, 19)

Answer 1

{5, 15, 19)

Explanation:

we know that in order to make sure the three sides represent a triangle, we have to this:

a+b>c

b+c>a

a+c>b

When doingthis to the four answer choices we get that the answer is:

{5, 15, 19) is correct since,

a=5

b=15

c=19

When we do the expression, we see that they are allm perfect and are greater then.

5+15>19

15+19>5

5+19 >15

Hope this helped!
