It's hard to explain, but I suggest you use the AC method. Hope this helps!
Answer:
x = 105
Step-by-step explanation:
the sum of all interior angles of any four-sided figure has 360 degrees
∡F and ∡H are equal
add all four expressions and set them equal to 360
x + (x + 5) +( x + 5) + (140 - x) = 360
combine like terms
2x + 150 = 360
2x = 210
x = 105
Your answer should be 1/6 because you are dividing thing by the number.
138,000/ 128,000 = 7.8125% Just divide new value into old value
