Answer:

x = 437.3 ft

Step-by-step explanation:

Look at the picture.

Use cosine:

[tex]cosine=\dfrac{adjacent}{hypotenuse}[/tex]

We have a measure of the angle and length of the hypotenuse:

[tex]\alpha=29^o,\ hypotenuse=500\ ft[/tex]

[tex]\cos29^o\approx0.87461[/tex]

Substitute:

[tex]\dfrac{y}{500}=0.87461[/tex]                 multiply both sides by 500

[tex]y=437.305\to y\approx437.3[/tex]
