An article in knee surgery, sports traumatology, arthroscopy (2005, vol. 13, pp. 273-279), considered arthroscopic meniscal repair with an absorbable screw. results showed that for tears greater than 25 millimeters, 13 of 18 repairs were successful while for shorter tears, 21 of 29 repairs were successful. (a) is there evidence that the success rate is greater for longer tears? use

the answer to the expression is 83

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

the answer is $42.96
