In the image, we have a triangle with an angle of 28° and another angle of 40°. The question asks for the value of $x$, which likely refers to the unknown angle in the triangle.

To solve for $x$, we can use the fact that the sum of the angles in any triangle is always 180°.

So, to find $x$: $x = 180^\circ - 28^\circ - 40^\circ$

Let’s calculate that: $x = 180^\circ - 68^\circ = 112^\circ$

Thus, $x = 112^\circ$.
