Answer:

Step-by-step explanation:

The two given angles add to 180 if the 2 angles that look parallel are parallel.

That means that

17x + 14 + 4x - 2 = 180        Combine like terms

21x + 12 = 180                     Subtract 12

21x = 180 - 12                      Combine

21x = 168                             Divide by 21

x = 168 / 21

x = 8

Therefore 17x + 14 is the angle you want.

<B = 17*8 + 14 = 150.

===================

There's another way to do this.

4x - 2 + <B = 180

4*8 -2 +<B = 180

32 -2 + <B = 180

30 + <B = 180

<B = 180 - 30

<B = 150
