Question

You are driving up an inclined road. After 3.0 km you notice a roadside sign that indicates that your elevation has increased by 160 m. What is the angle of the road above the horizontal?

Answer 1

~3°

Step-by-step explanation:

x^2 + 0.16^2 = 3^2

x^2 + 0.0256 = 9

x^2 = 8.9744

x = sqrt(8.9744) = 2.99... = ~3
