By the use of the trigonometric ratios, the height of the paraglide is 244 ft.
The trigonometric ratios are used to obtain the sides of a right angled triangle. In this case, the geometry of the problem can be reduced to a right angled triangle.
Thus we have;
sin 35 = x/400
x = 400 sin35 = 229 ft
Hence, height of the paraglider = 229ft + 15 ft = 244 ft
