Question

which equation could be used to find the value of m? m° m° 92° m + 92 = 180 2m + 92 = 90 2m + 92 = 180 m + 92 = 90

Explanation:

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

The sum of angles on a straight - line is 180°. Here, we have two angles of measure \(m^{\circ}\) each and one angle of measure 92°.

Step2: Set up the equation

The sum of these three angles is 180°. So, \(m + m+92 = 180\), which simplifies to \(2m + 92=180\).

Answer:

C. \(2m + 92 = 180\)
