In(36)=h/220ft
220ftsin(36) = h
h=129.3 ft

Answer:

The height of the pole 129.31 feet.

Step-by-step explanation:

Length of the pole = x

Length of the wire attached to the pole = 220 feet

Angle of elevation = $\theta =36^oC$

According trigonometric ratios::

$\sin \theta=\frac{Perpendicular}{Hypotenuse}$

$\sin36^oC=\frac{x}{220 feet}$

$0.5877=\frac{x}{220 feet}(sin36^oC=0.5877)$

x =129.31 feet

The height of the pole 129.31 feet.
