Question

If a triangle has side lengths of 5.6 yards, 7.1 yards, and x yards, find the range of possible values of x.

A.
1.5 < x < 12.7
B.
0 < x < 12.7
C.
0 < x < 1.5
D.
x > 1.5

Answer 1

longest side must be less than tehh sum of the other 2 sides
we cand find
minimum value of x is if it is shortest side
max value is if it is the longest side


if shortest side
7.1<5.6+x
minus 5.6 fom both sides
1.5<x

if it is longest side
x<5.6+7.1
x<12.7


1.5<x<12.7
