120

Step-by-step explanation:

We know <1 = 30 since it is a vertical angle

<2 = 60 since <1+<2  make a right triangle  ( a perpendicular to e)

<1 + <2   must equal 90

30+ <2 = 90

Since b is parallel to c

<2 = <4  so 4 = 60

<4 and <3  are corresponding angles, the add to 180 degrees

<4 + <3 =180

60 + <3 =180

<3 = 120 degrees
