Question

A triangle has the following measurements. What is a possible length for the third side?
AB = 5, BC = 7, CA = ?

Answer 1

Hint:

|a - b| < c < | a + b|

Answer 2

Basically, you can assume a = 5, b = 7, c = ?

Answer 3

So once to figure it out, there will be a range of c values that will make the triangle valid.

Answer 4

All you have to do is just input the values of a and b into that formula I gave you.

Answer 5

and remember that |x| means absolute value

Answer 6

is the answer 5

Answer 7

5 is one of several values that could work.

Answer 8

The range of values are

2 < c < 12

Answer 9

so 3,4,5,6,7,8,9,10, or 11 will work but nothing else
