Question

figure lmno is a parallelogram angles l and m are supplementary. what is the sum of their measures? the sum of the measures of angles l and m is °

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles are two angles whose sum is \(180^{\circ}\).

Step2: Apply the definition to angles \(L\) and \(M\)

Since angles \(L\) and \(M\) are supplementary, by the definition of supplementary angles, the sum of their measures is \(180^{\circ}\).

Answer:

180
