If f(x) = x, which of the following describes the graph of f(x) - 3?

part a) ratios of corresponding sides are equal

part b) cb=10

            ab=11.18

step-by-step explanation:

given:

δabc= 2δxyz

sinx=5/5.59

from trigonometric ratios we know

sinx=opposite side/hypotenuse

thus zy=opposite side=5

and xz= hypotenuse= 5.59

from pythagoras theorem we get

c^2= a^2 + b^2

xz^2=yz^2 + xy^2

5.59^2= 5^2 +xy^2

xy^2=6.2418

xy=2.5

part a)

when a triangle is multiplied or scaled by k, a constant scalar number to form another triangle then these two triangle are similar. and similar triangles have proportional lengths of corresponding sides. ratios within the triangle sides will be equal to the corresponding sides ratios of the other triangle. that is

xy/yz= ac/bc

xz/yz= ab/cb

yz/xz= bc/ab

          = ab/ac

part b)

from part a we know that

bc/ab=yz/xz

also yz/xz= 5/5.59

so bc/ab= 5/5.59

the scalar factor= 2

corresponding side of cb is yz, so

cb=2(yz)

      = 2(5)

      = 10

corresponding side of ab is xz, so

ab=2(xz)

      = 2(5.59)

      = 11.18!
