Which set of measurements could be the side lengths of a triangle? a. 5m, 11m, 7m b.10 m, 4 m, 5 m c.8 m, 4 m, 4 m d.6 m,11 m, 5 m

We know that
Triangle Inequality Theorem establishes that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
so
case A. 5M, 11M, 7M
5+11 > 7> ok
11+7 > 5 ---> ok
5+7 > 11> ok

case B.10 m, 4 m, 5 m
5+4 > 10> is not ok

case C.8 m, 4 m, 4 m
4+4 > 8> is not ok

case D.6 m,11 m, 5 m
6+5 > 11> is not ok

the answer is
A. 5M, 11M, 7M
