To find the height of the flagpole (\(x\)) and the distance between Ami and the top of the flagpole (\(y\)), we can use some basic trigonometry.

  1. Calculating the height of the flagpole \(x\):

    • According to the problem, Ami is looking at the flagpole from a distance of 50 feet at an angle of elevation of 35 degrees.
    • We can use the tangent function which relates the angle of elevation to the opposite side (height of the flagpole \(x\)) and the adjacent side (distance from Ami to the flagpole).

    \[ \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} = \frac{x}{50} \]

    Plugging in the angle:

    \[ \tan(35^\circ) = \frac{x}{50} \]

    Now, solving for \(x\):

    \[ x = 50 \cdot \tan(35^\circ) \]

    Using a calculator:

    \[ \tan(35^\circ) \approx 0.7002 \] \[ x \approx 50 \cdot 0.7002 \approx 35.01 \text{ feet} \]

  2. Calculating the distance \(y\) from Ami to the top of the flagpole:

    • To find \(y\), the distance to the top of the flagpole, we can use the sine function:

    \[ \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{x}{y} \]

    Rearranging gives:

    \[ y = \frac{x}{\sin(35^\circ)} \]

    We already found \(x \approx 35.01\) feet, so substituting:

    \[ y = \frac{35.01}{\sin(35^\circ)} \]

    Finding \(\sin(35^\circ) \approx 0.5736\):

    \[ y \approx \frac{35.01}{0.5736} \approx 61.04 \text{ feet} \]

In conclusion, the calculations yield:

  • Height of the flagpole \(x \approx 35.01\) feet
  • Distance from Ami to the top of the flagpole \(y \approx 61.04\) feet

Thus, the answer corresponds to x = 35.01 feet and y = 61.04 feet.
