A of both trianles = xsinQ[tex]\sqrt{x^2  x^2(sinQ})^2[/tex]
A of rectangle = (w2x)(xsinQ)
Total A = (w2x)(xsinQ) + xsinQ[tex]\sqrt{x^2  x^2(sinQ)^2}[/tex]
A = wxsinQ + 2x^{2}sinQ + x^{2}sinQcosQ
A_{x} = wsinQ + 4xsinQ + 2xsinQcosQ = 0
wsinQ = x(4sinQ + 2sinQcosQ)
x = w/(4 + 2cosQ)
A_{Q} = wxcosQ + 2x^{2}cosQ + x^{2}(sinQ)^{2}  x^{2}(cosQ)^{2} = 0
It gets pretty messy when i plug in x, are there anny errors so far
