A triangle has two sides of lengths 4 and 15. What value could the length of the third side be? Check all that apply.
A. 4
B. 12
C. 19
D. 15
E. 11
F. 13
The third leg can vary from A-B to A+B but not including those two values.
In this case, A=15, B=4, the final leg can range from 11 to 19.
So
13
15
12
