Roberta has three pieces of pipe. Pipe A is 7 feet long, pipe B is 8 feet long, and pipe C is 3 feet long. If the full length of each pipe is used, can the three pieces of pipe be placed together to make a triangle?

1. Yes, 7+3>8

2. Yes, 8-3>7

3. No, 8-7<3

1. Yes, 7 + 3 > 8

Step-by-step explanation:

The triangle inequality theorem says that to make a triangle, the lengths of any two sides of a triangle have to be greater than the length of the third side.

These three pipes can be used to form a triangle.

7 + 8 > 3

7 + 3 > 8

8 + 3 > 7

So, the correct answer is 1. Yes, 7 + 3 > 8
