a and b are parallel because 114 = 66+48 = 114, these two angles are the same because they are alternate exterior angles, and they couldn't be the same if a and b are not parallel.
Here, You need to calculate the slope of the graph by taking any two random points, as follows:
(x₁,y₁) = (0,0) & (x₂,y₂) = (1,55)
Now, we know,
y₂-y₁ = m(x₂-x₁)
55-0 = m(1-0)
m = 55/1
m = 55
Here m represents the slope of graph which is nothing but rate of change of distance.
In short, option A will be your answer.
Hope this helps!
Answer:
Answer = 0.25
Step-by-step explanation:
Slope (m) = 0.25
θ = 14.036243467926°
distance (d) = 74.215901261118
ΔX = 72
ΔY = 18
0.12 because it equals to 12% where 1.2% equals to 0.012
