To find the length of the kite string (x), we can use trigonometry. Given the distance from the base of the kite (14 meters) and the angle of elevation (67°), we can use the cosine function:

\[ \cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}} \]

where:

  • \(\theta = 67°\)
  • adjacent side = 14 m (the distance from the base)
  • hypotenuse = x (the length of the kite string)

Rearranging this formula to find \(x\):

\[ x = \frac{\text{adjacent}}{\cos(\theta)} \]

Now, substituting the known values:

\[ x = \frac{14}{\cos(67°)} \]

Calculating \(\cos(67°)\):

\[ \cos(67°) \approx 0.3907 \]

Now plug that into the equation:

\[ x = \frac{14}{0.3907} \approx 35.83 \text{ m} \]

So, rounding to the nearest hundredth, the length of the kite string is:

\[ \boxed{35.83 \text{ m}} \]
