Answer 1

To determine the possible values of the third side \( c \) of a triangle with the other two sides measuring \( a = 34 \) and \( b = 51 \), we can use the Triangle Inequality Theorem, which states that for any triangle with sides \( a \), \( b \), and \( c \):

1. \( a + b > c \)
2. \( a + c > b \)
3. \( b + c > a \)

We can apply these inequalities:

1. From \( a + b > c \):
\[
34 + 51 > c \implies 85 > c \implies c < 85
\]

2. From \( a + c > b \):
\[
34 + c > 51 \implies c > 51 - 34 \implies c > 17
\]

3. From \( b + c > a \):
\[
51 + c > 34 \implies c > 34 - 51 \implies c > -17
\]
(This last inequality does not provide additional constraints since \( c > 17 \) is a stronger condition.)

Putting these inequalities together, we have the final range for the third side \( c \):

\[
17 < c < 85
\]

Thus, the inequality indicating the possible values of the third side \( c \) of the triangle is:

\[
17 < c < 85
\]
