Victoria drives 150 meters up a hill that makes an angle 12 degrees with the horizontal. to nearest tenth of a meter, what horizontal distance has she covered.
answers:
a:153.4 meters
b:146.7 meters
c:31.9 meters
d:31.2 meters
We can use the cosine....
cos (12 ° ) = H / 150 where H is the horizontal distance.....multiply both sides by 150
150 * cos (12°) = H ≈ 146.7 m
