How many triangles can be made from the following three lengths: 2.7 centimeters, 8.6 centimeters, and 4.8 centimeters?

one
none
more than one

Answer 1

none

Explanation:

Hi, I hope this helps, I'm in high school LOL.

Use these, they help to figure this out:

a + b > c

b is the longest side, or hypotenuse. c would be the base.

We have to make sure that c is less than what a + b is.

Plug the numbers in:

2.7 + 4.8 > 8.6

4.8 plus 2.7 is 7.5 cm.

So, 7.5 > 8.6

Obviously, 7.5 is less than 8.6 so 7.5 > 8.6 does not work at all.

That tells you that no triangles can be formed. So, it's none.
