4. At the scene of a crime, you find three patterns of blood spots. You measure the following lengths and widths for each spot: 1. Spot A pattern: Length = 4.0 mm, Width = 4.0 mm
2. Spot B pattern: Length = 3.0 mm, Width = 1.5 mm
3. Spot C pattern: Length = 5.0 mm, Width = 1.0 mm
Use the formula given above to determine the angle of impact for each of these three bloodstain patterns. Which dropped from a point directly overhead? Which impacted at the sharpest angle? As a blood spatter analyst, how would you interpret and use this information? Explain.

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
