The correct option is 350.62 feets.

Step-by-step explanation:

Let the triangle Δ ABC

the length of wire = AC

Height of the pole = AB

Length between the point of attachment of wire from base of the pole = BC = 137 feets

Angle of elevation to the pole = θ = 67 °

According to trigonometry :

cosθ = $\frac{base}{hypotenuse}$

cos 67 ° = $\frac{BC}{AC}$

$0.39=\frac{137}{AC}$

AC = 351.28 feets $\approx$ 351 feets.

From the given option the closest value to our answer is 350.62 feets.

Hence, the correct option is 350.62 feets.
