All I want is a hint/ starter on this problem No need to answer. Just bunked on how to start.
A good start is always to draw in the information from the question So put S² in the rectangle and als write in an equation what that means using the symbols from the figure It might also be of use to draw which angles are square, and which angles are the same Writhing down all info you can get from the figure using Pythagoras (3 times)
From the triangles of similar shape what ratioś are the same?
AB/AG = AD/AE =BD/BF ? not sure haven't done geo in a while
AB/BD is a already given, which are the same as that ratio?
AG/GE
yes, and another one as well
EF/FD
yes
But I do not know how to translate my only set of numbers into the rest of the proportions
You will have to express the answers also in terms of S
Right now I have 8/10 = AG/GE = EF/FD not sure where to go with this
s= bh

Iĺl need a while to figure this one out

Triangles AGE and ABD are similar. Therefore, AG / GE = AB / BD (8-y) / x = 8 / 10 = 4 / 5 cross multiply: 40 - 5y = 4x 4x + 5y = 40 ------ (1)
AB^2 + BD^2 = AD^2 AD^2 = 8^2 + 10^2 = 164 AD = sqrt(164) AE^2 = AG^2 + GE^2 = (8-y)^2 + x^2 AE = sqrt{ (8-y)^2 + x^2 } ED^2 = EF^2 + FD^2 = y^2 + (10-x)^2 ED = sqrt{ y^2 + (10-x)^2 } AD = AE + ED sqrt(164) = sqrt{ (8-y)^2 + x^2 } + sqrt{ y^2 + (10-x)^2 } ------ (2) Solve (1) and (2) for x and y.
Oh wow, still quite confusing honestly thing this problem would be easier with trig o.e
Can the answer be in terms of "S" ?
Not sure, that screenshot is all I was given not sure if S is needed as we are only looking for GE and EF
