Question

ased on these triangles, which statement about x is true?
x = 340
x = 20
x = 160
x = 80

Explanation:

Step1: Recall the 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 \(x\)

For the triangle with interior angles \(30^{\circ}\) and \(130^{\circ}\), let the exterior angle be \(x\).
By the exterior angle theorem, \(x = 30+130\)

Answer:

\(x = 160\)
