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?

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

 The horizontal distance she has covered is:

x=483.0m

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
