line l is parallel to line m. If the measure of 6 is 75°, wat is the measure of 4?

Given data:
The given figure.
The expression for the alternate angle is,
[tex]\angle4=\angle6[/tex]Substitute the given value in the above expression.
[tex]\angle4=75^{\circ}[/tex]Thus, the measurement of the angle 4 is 75 degrees.
