Hey ya'll! I'm posting another question like the one I just posted. Do you think you guys can help me out with this or tell me how I can do it? I'm not that good at geometry. Thank you so much if you do!

The sum of any two sides must be greater than the third side to physically form
the triangle, so is ...
20.2 + 11 > 8.2 ?
is 20.2 + 8.2 > 11 ?
is 11 + 8.2 > 20.2 ?
if the answer to any of those is NO, then you can't have a triangle
the triangle, so is ...
20.2 + 11 > 8.2 ?
is 20.2 + 8.2 > 11 ?
is 11 + 8.2 > 20.2 ?
if the answer to any of those is NO, then you can't have a triangle

okay, so judging by the explanation, I need to find the sum of the math you gave me, and if the first two are greater then the third expression, then it can form a triangle? am I understanding right?

I looked the expressions up and this is the results
1. true
2. true
3. false
does this mean I can form a triangle?
1. true
2. true
3. false
does this mean I can form a triangle?

did you not read my last line ?
"if the answer to any of those is NO, then <b>you can't have</b> a triangle"
