Supplementary angles add up to 180 degrees.
x + 107 = 180
x + 107 - 107 = 180 - 107
x = 73
The correct answer is B. 73 degrees.
Hope this helps =)

Answer:
All you have to do is to the distributive method.
Step-by-step explanation:
(7x+14)(9x-8)
2(3x - 4) = 5x + 20
6x - 8 = 5x + 20
subtract 5x from both sides
x - 8 = 20
add 8 to both sides
x = 28
