Question

Describe the possible lengths of the third side of a triangle given that the lengths of the other two sides are 5 and 12 units long. Please express your response as a compound inequality.

Answer 1

7<x<17

Explanation:

a+b>x

5+12>x

17>x

5+x>12

x>7

12+x>5

x>-7 (ignore then since it is negative and you would use the one that makes the range smaller which is the one above)
