Viola drives 170 meters up a hill that makes an angle of 6° with the horizontal. to nearest tenth of a meter, what horizontal distance has she covered?

a. 171.5m

b. 169.1m

c. 1617.4m

d. 17.8m

This is the concept of trigonometry, to get the horizontal length we use the formula:

cos θ = (Adjacent) / (hypotenuse)

θ=6°

adjacent=x

hypotenuse=170m

thus the value of x will be:

x/170=cos6

hence:

x=170 cos 6

x=169.06872 meters

Answer: 169.06872 m
