Valerie drives 500 meters up a hill that makes an angle of 15° with the horizontal. to the nearest tenth of a meter, what horizontal distance has she covered?

For this case we can model the problem as a rectangle triangle.
 We know:
 Length of the hypotenuse
 Angle between the base of the triangle and the hypotenuse.
 We want to know:
 Length of the base.
 For this we use the following trigonometric relationship:
 
 Clearing x we have:
 
 Rounding to the nearest tenth of a meter:
 
 
 The horizontal distance she has covered is:
 

The answer is

Omg that is a big question and weird words and i’m only 5
