Question

if there is a triangle, one side is 18 ft long, other is 23ft, how long is the last side? medal given :)

Answer 1

The sum of the lengths of any two sides of a triangle must be greater that the length of the third side.
You have 18, 23 and x

Add 18 and 23 and compare to x
18 + 23 > x
41 > x
x < 41

Now add 18 and x and compre to 23
18 + x > 23
x > 5

Now add 23 and x and compare to 18
23 + x > 18
x > -5
Since we already know x must be greater than 5, we don't need this constraint.

5 < x < 41
x must be between 5 and 41

Answer 2

if its Regular Almost ( x = 14 ft)
