OpenStudy (helder_edwin):

is there more information?

OpenStudy (anonymous):

no :(

OpenStudy (anonymous):

Geometric Mean time. For the first part: \[\frac{EH}{GH} = \frac{GH}{HF}\]Plug in your known values and tell me what you get.

OpenStudy (anonymous):

yea i got the answer for the first one

OpenStudy (anonymous):

thank you calcmathlete

OpenStudy (helder_edwin):

you can solve the following system \[ a^2+c^2=(5+28.8)^2 \] \[ 5^2+b^2=a^2 \] \[ c^2=b^2+28.8^2 \] where a=EG, b=GH and c=GF Try it!

OpenStudy (anonymous):

Yeah. You can do that or you can also use geometric means again. \[\frac{EH}{EG} = \frac{EG}{EF}\]and\[\frac{HF}{GF} = \frac{GF}{EF}\]

OpenStudy (anonymous):

it help me thank u calcmathlete and helder_edwin
