None. The triangle inequality states that the sum of the smaller two sides of a triangle must be greater than the third side. As 4+5=9, this inequality is false in this case, so these sides cannot create a triangle.
The altitude of the kite: h = 5 + 250 · sin 45° h = 5 + 250 · √2 / 2 h = 5 + 250 · 0.7071 = 5 + 176.77 = 181.77 ≈ 182 ft Answer: The altitude is 183 ft.
