Question

PLEASE ANYTHING HELPS!

Valerie drives 500 m up a hill and in angle of elevation of 15° To the nearest tenth of a neater what horizontal distance has she covered?

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
