Answer:
Using the relation between the sides of a triangle, the answer is True.
Step-by-step explanation:
The length are 5, 7 and 10.
In any triangle:
1) The sum of the lengths of any two sides is greater than the length of the third side.
5+7=12 > 10 ok
5+10=15 > 7 ok
7+10=17 > 5 ok
2) The difference between the lengths of any two sides is less than the length of the third side.
7-5=2 < 10 ok
10-5=5 < 7 ok
10-7=3 < 5 ok
