Answer:
x= 11
Step-by-step explanation:
Answer:
<h2>x = 745.5 ft</h2>
Step-by-step explanation:
Look at the picture.
Use sine:
![sine=\dfrac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sine%3D%5Cdfrac%7Bopposite%7D%7Bhypotenuse%7D)
We have a measure of the angle and length of the opposite:
![\alpha=28^o,\ opposite=350\ ft](https://tex.z-dn.net/?f=%5Calpha%3D28%5Eo%2C%5C%20opposite%3D350%5C%20ft)
![\sin28^o\approx0.4695](https://tex.z-dn.net/?f=%5Csin28%5Eo%5Capprox0.4695)
Substitute:
![\dfrac{350}{x}=0.4695](https://tex.z-dn.net/?f=%5Cdfrac%7B350%7D%7Bx%7D%3D0.4695)
<em>cross multiply</em>
<em>divide both sides by 4695</em>
![x=\dfrac{3500000}{4695}\to x\approx745.5](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B3500000%7D%7B4695%7D%5Cto%20x%5Capprox745.5)
