The 15 foot ramp must make an angle 19.45° with the ground to reach the same window.
What angle must be made with the ground by the 15 foot ramp?
Since the height of the window above ground remains constant in both cases, it follows that by means of trigonometric identity sine; we have;
10sin30° = 15sinx
sinx = 5/15 = 0.333
x = sin-¹(0.333)
x = 19.45°.
