There are more than 4 values.
1) First draw up a triangle that looks possible.
All the angles are different so if you use a triangle that looks a bit like a 30,60, 90 degree triangle that will be good to work with.
2) Label the 3 angles correctly according to their relative angle size
3) Label the 3 sides
4) Now the smallest side is opposite the smallest angle etc so write 'smallest' and 'biggest' near the correct sides.
5) Now you know that smallest side < middle side Solve the inequality
6) You also know that the middle side < longest side. Solve the inequality.
7) So what do you know so far?
8) Now to be a triangle at all the sum of the 2 smallest sides must be longer than the long side.
Form the inequality and solve it.
9) So what have you found.
If you have questions then ask. You can take a photo of your pic on your phone and post it if need be.
I am very happy to help more if necessary but i want to be convinced that you are trying to help yourself first.
Please no one else answer
