Question

find the value of x.
x = \boxed{}

Explanation:

Step1: Recall triangle exterior angle theorem

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

Step2: Apply the theorem to find x

Here, the two non - adjacent interior angles are \(35^{\circ}\) and \(88^{\circ}\). So, by the exterior angle theorem, \(x = 35+88\).
Calculating the sum: \(35 + 88=123\).

Answer:

\(x = 123\)
