Kevin was asked to determine the length of side xz. his work is shown. cos(34°) = (xz)cos(34°) = 18 xz =21.7 which error did kevin make? he has the side lengths in the wrong place in the cosine ratio. he multiplied both sides by the length of xz instead of dividing by xz. he should have used the sine ratio. he should have used the tangent ratio.

Hello from MrBillDoesMath!

t = i /(Pr)

Discussion:

i = Prt   =>     (divide both sides by "Pr")

i/(Pr) = (Prt)/(Pr)

        = (Pr)t/(Pr)

        = t                      (as (Pr)/(Pr) = 1)

Thank you,

MrB
