a telephone pole shown at the top of the next column is 60 feet tall. a guy wire 87 feet is attached from the ground to the top of the pole. find the a as angle between the wire and the pole to the nearest degree.

This problem involves a right triangle, where:

- The height of the telephone pole is 60 feet.
- The length of the guy wire is 87 feet.

We are asked to find the angle \( \theta \) between the guy wire and the pole. This angle is located between the pole (the vertical side) and the guy wire (the hypotenuse).

To solve for \( \theta \), we can use the sine function, since we know the opposite side (the height of the pole) and the hypotenuse (the length of the wire).

\[
\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{60}{87}
\]

Now, calculate \( \theta \) by taking the inverse sine (arcsin):

\[
\theta = \sin^{-1}\left(\frac{60}{87}\right)
\]

\[
\theta \approx \sin^{-1}(0.6897) \approx 43.58^\circ
\]

Rounding to the nearest degree:

\[
\theta \approx 44^\circ
\]

Thus, the angle between the wire and the pole is approximately **44 degrees**.
