Question

find the value of n.

Explanation:

Step1: Recall exterior - angle property

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

Step2: Identify non - adjacent interior angles

The non - adjacent interior angles to the exterior angle $n^{\circ}$ are $54^{\circ}$ and $71^{\circ}$.

Step3: Calculate the value of $n$

$n=54 + 71$
$n = 125$

Answer:

$125$
