Answer:
15.3 inches
Explanation:
Given that :
a blood drops on the ground at 2mm wide and 5mm long; it is possible to determine the angle of impact.The angle of impact is the angle at which blood stains appear on the surfaces.
angle of impact = [tex]sin^{-1} \frac{width}{length}[/tex]
angle of impact = [tex]sin^{-1}( \frac{2}{5})[/tex]
angle of impact = [tex]sin^{-1}(0.4)[/tex]
angle of impact = 23.59
The point of origin is the height at which the blood falls from and which is calculated as follows:
Tan θ = opposite/adjacent
Tan θ = height at which the blood is falling from /distance
Tan 23.59° = x/35 inches
x = Tan 23.59° × 35 inches
x = 0.43668 × 35 inches
x = 15.2838 inches
x ≅ 15.3 inches
Thus; the point of origin is 15.3 inches high off the ground
