$1.$ Given: The A$-$frame roof structure shown below supports a distributed load $"$w$1"=12$ kN$/$m$.$ The distances are $"$y$1"=0\mathrm{.}75$ m$,"$y$2"=0\mathrm{.}95$ m and $"$y$3"=3\mathrm{.}30$ m$.$ The angle $"$Q$"=58$ degrees and the angle $"$F$"=71$ degrees. Distances $"$d$1"$ and $"$d$2"$ need to be calculated. Calculate: Calculate the horizontal and vertical components of the reactions at the supports $"$A$"$ and $"$E$"$ and the magnitude of the resultant force at pin $"$C$".$
