Given ΔMNO, find the measure of ∠LMN.

Triangle MNO with segment LM forming a straight angle with segment MO and segment OP forming a straight angle with segment MO, the measure of angle NOP is 104 degrees, and segment MN and NO are marked congruent.

38°

52°

76°

104°

The last one, 104 degrees

104°

Step-by-step explanation:

Thinking process:

Let the triangle be:

ΔMNO

The angle be: ∠LMN.

From the description, NOP is 104°

If, segment MN and NO are marked congruent then the corresponding angle, ∠LMN is 104°

This property of congruency applies since the segments are equal.
