Mason wants to use a sheet of fiberboard 21 inches long to create a skateboard ramp with a height of inches at its highest end. Find the angle of elevation made by the ramp with the ground. Round your answer to the nearest tenth of a degree.

It appears that the height of the skateboard ramp is missing from the problem statement. To determine the angle of elevation (\(\theta\)) that the ramp makes with the ground, we need two key measurements: 1. **Length of the ramp (hypotenuse)**: 21 inches 2. **Height of the ramp (opposite side)**: *[Missing]* The relationship between the angle of elevation, the opposite side (height), and the hypotenuse (ramp length) can be described using the sine function in trigonometry: \[ \sin(\theta) = \frac{\text{Opposite}}{\text{Hypotenuse}} = \frac{\text{Height}}{21} \] To find the angle \(\theta\), you would use the inverse sine (arcsin) function: \[ \theta = \arcsin\left(\frac{\text{Height}}{21}\right) \] **Action Required:** Please provide the height of the skateboard ramp in inches so that I can help you calculate the angle of elevation accurately.
