Question

find the measure of the exterior angle.
the measure of the exterior angle is 130 × °.

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 exterior angle

Let the exterior angle be \(k\). Using the theorem, \(k = 64+76\).

$$k=140$$

Answer:

\(140\)
