Three$-$position synthesis by multiple methods. Solve this problem:

a$.$ Using graphical techniques $($with rectification$)$

b$.$ Using complex$-$number analytical synthesis $($Cramer$$s Rule$).$

i$.$ Use $\backslash$beta $2=25\backslash$deg $,\backslash$beta $3=70\backslash$deg for the first dyad, and $\backslash$beta $2=-15\backslash$deg $,\backslash$beta $3=-45\backslash$deg for the

second dyad.

c$.(2$ pts EC$)$ Using ground pivot specification

positioning ground pivot Oa at $-5+-5$i$.$
