Question

find the value of x.

Explanation:

Step1: Apply the exterior angle theorem

The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Calculate the value of \(x\)

Here, the two non - adjacent interior angles are \(40^{\circ}\) and \(104^{\circ}\). So, \(x=40 + 104\).

$$x=144$$

Answer:

$x = 144$
