Question

use the image provided
which two angles when added together equal the measurement of ∠8?
∠1 + ∠4
∠7 + ∠4
∠9 + ∠7
∠9 + ∠4

Explanation:

Step1: Use 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: Identify the exterior angle and non - adjacent interior angles

In the given image, \(\angle8\) is an exterior angle of the triangle. The non - adjacent interior angles of the triangle with respect to \(\angle8\) are \(\angle4\) and \(\angle9\).

Answer:

\(\angle9+\angle4\)
