Answer:
answer is 6 cm, 7cm, 12 cm
Step-by-step explanation:
the rule is that the sum of any two sides of a triangle must be greater than the 1 one side
174 is equal to 174 if thats what the last one means
When the length of sides are given, you can use law of cosine to find the angles
Refer to this website for details

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25
