Question

solve for n

Explanation:

Step1: Recall triangle exterior angle rule

An exterior angle of a triangle equals the sum of the two non-adjacent interior angles.

Step2: Identify relevant angles

The exterior angle is $n$, and the two non-adjacent interior angles are $61^\circ$ and $87^\circ$.

Step3: Calculate $n$

$n = 61^\circ + 87^\circ$

Answer:

$148^\circ$
