Find the total horizontal wind loads for load cases A and B using the envelope procedure$-$part $2$ of ASCE $7-10$ for a $2-$story building with sides $L_{\text{m}\text{a}\text{x}}=120ft$ and $L_{\text{m}\text{i}\text{n}}=80ft,$ and story heights $h_i=14ft.$ The building has a gable roof with angle $=5,$ exposure category B $,$ topographic factor $K_{zt}=1,$ and no overhang. The design wind speed is $125$ mph $.$ Explain$/$justify all your calculations by providing appropriate references to equations$/$tables$/$figures in ASCE $7-10.$

Note: only horizontal loads are required $($you do not need to compute the uplift forces for this assignment$)$
