You can use three  properties of angles on intersecting lines:

(1) similar angles of two parallel lines intersected by a third line

(2) vertically opposite angles equality

(3) supplemental angle

So:

Step 1: <8 = <4    (due to line being parallel, angles are similar)

<4 = 147 deg

Step 2:

<2 = <4

<2 = 147 deg

Step 3:

<3 = 180-<2   (supplemental angle)

<3 = 33 degrees

Answer:

m<2 = 147 deg

m<3 = 33 deg
