In linear change, the two variables keep increasing or decreasing at the same speed.
Answer:
∠ EFH = 112°
Step-by-step explanation:
∠ ACD and ∠ EFH are Alternate exterior angles and are congruent, thus
11x - 20 = 9x + 4 ( subtract 9x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Thus
∠ EFH = 11x - 20 = 11(12) - 20 = 132 - 20 = 112°
we have

the solution is the interval -------> (3,∞)
therefore
the answer in the attached figure
40% of 85 is 34 so 85-34=51
51 is your answer
