Question

Tell whether a triangle can have sides with these lengths and explain:
6.2, 8.1, 14.2

Answer 1

I need help in general in figuring out how to determine if numbers can make a triangle.

Answer 2

the two smaller sides of a triangle need to have a sum (together) greater (at least a bit greater) than the measure of the largest side.

Answer 3

For example, \(\normalsize\color{blue}{ \rm 4,~6,~10 }\) is NOT a triangle.

Answer 4

But,
\(\normalsize\color{blue}{ \rm 3,~~4.1,~~7 }\) is a triangle, because \(\normalsize\color{blue}{ 3+4.1>7 }\).

Answer 5

okay awesome thank you!

Answer 6

I was about to explain more, but you already got it:D good job!
