To find the angle the ladder makes with the ground, we can use trigonometry. The height the ladder reaches up the wall (23.4 feet) is the opposite side, and the length of the ladder (26 feet) is the hypotenuse. We can use the sine function: \[ \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{23.4}{26} \] Calculating that gives us: \[ \sin(\theta) \approx 0.9 \] Now, to find \(\theta\), we take the inverse sine: \[ \theta = \sin^{-1}(0.9) \approx 64.16^\circ \] Rounding to the nearest tenth gives: \[ \theta \approx 64.2^\circ \] So, the angle the ladder forms with the ground is approximately 64.2 degrees.
