Answer:
36 °
Step-by-step explanation:
In this case a rectangular triangle is formed so we can use the trigonometric functions to calculate the angle, they give us the value of the two legs, therefore we can apply the tangent function.
Tan A ° = opposite / adjacent
replacing:
Tan A ° = 50/68
Tan A ° = 0.735
A ° = arc tan (0.735)
A ° = 36.32
Which means that the angle of inclination is 36°
Circumference (C) = 2 π·r ; where r is the radius = diameter(d)/2
C = 2 π·(14/2)
=2 π·(7)
= 14π
I think the answer is 35 km per hour because they are travelling in steady rate and the graph chart is showing the times and all
