Answer:
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
