Question

PLEEEEEEEEEEEEEEEEEEASE HEEEEEEEEEEEEEEELP!

Answer 1

Let a, b, and c be the length of 3 corresponding sides of the triangle. The following inequality must always be true since they form a triangle :

$a+b>c$

(This inequality says that the sum of two sides must always be greater than the other side)

Let's use this inequality for x, 1.3, and 4.1

$x+1.3>4.1$

(The reason why 1.3 is on the left side is because it is the smaller side)

Subtract both sides by 1.3

$x>2.8$

x must always be greater than 2.8. Now, let's see what value x must be always less than.

$1.3+4.1>x$

$5.4>x$

x must be always less than 5.4. Let's combine both statements for x and we get:

$2.8$

These are the only values of x that will make it possible for these sides to form a proper triangle.

Let me know if you need any clarifications, thanks!
