Given : Ahmed is driving on a road .He observed that road is inclined at the angle of 6 degree.He traveled 1.5 km on this inclined road
To find : How high above road level is Ahmed
Solution:
road is inclined at the angle of 6 degree
Sin 6° = ( height of road at that point )/ ( distance Covered)
distance Covered = 1.5 km = 1500 m ( as 1 km = 1000 m)
height of road at that point = h m
=> Sin 6° = h / 1500
=> 0.1045 = h/1500
=> h = 156.8
156.8 m high above road level is Ahmed
