Question

PLEASE ANYTHING HELPS!

Answer 1

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:

cos(15)=x/100

 Clearing x we have:

x=500*cos(15)

x=482.96

 Rounding to the nearest tenth of a meter:

x=483.0m

 Answer:

 The horizontal distance she has covered is:

x=483.0m
