Difference 83079

On the traffic sign that informs about the road's gradient, the figure is 6.7%. Determine the slope angle of the path. What height difference is covered by the car that traveled 2.8 km on this road?

Correct answer:

α =  3.8331 °
h =  187.6 m

Step-by-step explanation:

r=6.7%=1006.7=0.067  r = y:x = tan α  A=arctanr=arctan0.067=0.0669 rad  α=A  °=A π180   °=0.0669 π180   °=3.833  °=3.8331=3°4959"
s=2.8 km m=2.8 1000  m=2800 m  h=r s=0.067 2800=187.6 m
