Given:


m\angle5=143^(\circ)
\angle1\text{ and }\angle5\text{ are corresponding angles.}

Corresponding angles are equal.


m\angle1=143^(\circ)
\angle1\text{ and }\angle3\text{ are vertically opposite angles.}

Vertically opposite angles are equal.


m\angle3=143^(\circ)

Sum of the angles in a straight is 180 degree.


m\angle2+m\angle3=180^(\circ)
m\angle2=180-143
m\angle2=37^(\circ)

Therefore,


m\angle2=37^(\circ)\text{ and m}\angle3=143^(\circ)
