Two sides of a triangle have lengths of 7 and 15. Which inequality represents the possible lengths for the third side?
kirill115 [55]

Answer:

D

Step-by-step explanation:

From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:

7+15>x

However, 15 can also be our largest side. So:

7+x>15

Let's solve for x for both inequalities.

First inequality:

7+15>x

Add:

22>x

Flip:

x

Second inequality:

7+x>15

Subtract 7 from both sides:

x>8

So, we have the compound inequality:

x>8\text{ and } x

Combine:

8

Our answer is D

And we're done!
