Answer:

x ≈ 745.5 ft

Step-by-step explanation:

The angle at the lower right of the triangle is 28° ( alternate angle )

Using the sine ratio in the right triangle

sin28° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{350}{x}[/tex]

Multiply both sides by x

x × sin28° = 350 ( divide both sides by sin28° )

x = [tex]\frac{350}{sin28}[/tex] ≈ 745.5 ft ( to the nearest tenth )
