which equation can be used to find the value of x?
$x = 72 - 68$
$x = 68 + 72$
$x + 68 + 72 = 180$
$x + 68 + 72 = 360$

Explanation:

Step1: Recall the triangle angle - sum property

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Set up the equation

If the angles of a triangle are \(x^{\circ}\), \(68^{\circ}\), and \(72^{\circ}\), then by the triangle angle - sum property, \(x + 68+72 = 180\).

Answer:

\(x + 68 + 72 = 180\)
