BRAINLIESTT ASAP! PLEASE HELP ME :)

Answer 1

According to the triangle inequalities rule, the sum of any 2 sides has to be greater than that of the the third side.

We can write two inequalities to resemble this problem.

x + 15 > 19 and 15 + 19 > x

Now, solve for x for both inequalities.

Steps to solve:

x + 15 > 19

~Subtract 15 to both sides

x + 15 - 15 > 19 - 15

~Simplify

x > 4

Steps to solve:

15 + 19 > x

~Simplify

34 > x

We can put both inequalities together to get:

4 < x < 34

The only value from the list of options that can be "x" is 6.

Therefore, the answer is 6cm (Option A)

Best of Luck!
