A²+B²=C²
6²+8²=C²
C²=100
C=10
Therefore the length of AB is 10 units
They won 20/30, so 100 / 30 = 3.3, then times by 20 = 66.66.
Hope this helps.
D.the number of times the drug has removed a certain percentage of fluid from the patient's lungs
From the figure, the vertices of the given triangle are
(-3,4), (1,3) and (5,5).
The given transformation is (x,y) -> (x+3, y-2).
Therefore the coordinates of the transformed triangle are
(-3+3,4-2), (1+3,3-2), (5+3,5-2) = (0,2), (4,1), (8,3)
The transformed triangle is shown in red color.
