Question

what is the measure of the exterior angle x? (1 point)

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 \(37^{\circ}\) and \(42^{\circ}\). So, \(x = 37+42\).

$$x=37 + 42=79$$

Answer:

\(79^{\circ}\)
