Please help me solve this.Will award full points to full work shown!

For the truss shown, determine Any zero-force members through inspection only The forces in members AB, AL, DE, DG, EF, EG, FG, and GH through the method of joints The forces in members CD, CH, and HI through the method of sections **You must solve for CD, CH, and HI with equations where each member is the only member in the equation (for example, you cannot use CD in an equation that solves for CH even if you know CD - CH must be the only member in the equation).

Explanation / Answer

first draw the free body diagram and then u get forces at A and L at A u have Ax and Ay and at L u have Lx X aixs is above and y axis is towards right now net forces on X and Y axis are zero so u get Ax+Lx=10+15+10+20*cos(30) Ly=20*sin(30) now consider the moment equations about A so u get Ly*10=20*cos(30)*10+10*15+15*20+10*25 so u will get the values of Ax and Lx Now consider A u have four forces write the equations at that point u will get 2 set of equations and so on u will get the equations and u need to solve zero force members:BI,HI,HG and GF
