First see if there is a constant rate of change...
(344.8-346)/(2-0)=-0.6
(343-344.8)/(5-2)=-0.6
So the rate is constant which means this is just a line of the form y=mx+b
m=-0.6 and since we see that (0,346) we know the y-intercept, "b", is 346 so our line is:
y(x)=-0.6x+346
y(4)=343.6 ft
y(9)=340.6
6.8 + 8.75 = 11.55

Right angle triangle
answer is (C)
Answer:
Choice A.
Step-by-step explanation:
tan < ABC = 60/40
So m < ABC = 56.31 degrees.
This makes m < DBC = 56.31 / 2 = 28.15 degrees
tan 28.15 = DC / 40
DC = 40 tan 28.15
= 21.407 ft.
