Part a) The elevation of the road is
Part b) The rise is
Step-by-step explanation:
Part a) What is the elevation of the road to the nearest degree?
Let
y-----> the rise of the road ( vertical distance)
x ----> the run of the road (horizontal distance)
we have
y/x=1/10
we know that
The ratio y/x is equal to the tangent of the angle of the elevation of the road
Let
----> angle of the elevation of the road
Part b) If the road is two km long, how much does it rise?
using proportion
Answer:
x = 5
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
Step 2: Check if solution is correct.
