lauren is designing a metal sculpture that contains a triangle with sides of 4 inches and 11 inches. She is trying to determine

lesya692 [45]

Answer:

$7 < x$

Step-by-step explanation:

Let

x ----> the length of the third side of triangle in Lauren's sculpture

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the Triangle inequality Theorem

1) $4+11 > x$

$15 > x$

Rewrite

$x< 15\ in$

2) $4+x > 11$

$x> 11-4\\x> 7\ in$

therefore

The possible values of x are

$7\ in < x$
