Answer:
35 degrees
Explanation:
Angle LMN has a measure of 35 degrees.
The angle is rotated 75 degrees about point M.
First, we note that a rotation is a rigid transformation. A rigid transformation does not change the shape or size of the object.
What this means is that angle LMN will retain its shape and measure after a rotation.
Thus, the measure of angle L'M'N' is 35 degrees.
