The tailgate of the moving truck is 2 feet above the ground as shown in figure. And the inclination of ramp used for loading the truck is $15 掳$ .

Step 2. Calculation.

From the given, figure it can be interpreted that in triangle ABC $A B = 2 ft and C = 15 掳$ . Therefore, by trigonometric ratios,

$\begin{matrix} \sin (C) = \frac{A B}{A C} \\ \sin (15 掳) = \frac{2}{A C} \\ A C = 2 \csc (15 掳) \\ A C = 7.7 foot \end{matrix}$

Step 3. Conclusion.

The length of the ramp is $7.7 foot$ .
