Question

what is the value of n? 26.5° 72.5° n

Explanation:

Step1: Recall angle - sum property of a straight - line

The sum of angles on a straight - line is 180°.

Step2: Set up the equation

We know that \(n + 26.5^{\circ}+72.5^{\circ}=180^{\circ}\).

Step3: Solve for \(n\)

First, add the known angles: \(26.5^{\circ}+72.5^{\circ}=99^{\circ}\). Then, \(n=180^{\circ}-99^{\circ}\).
