Given the following three$-$dimensional pipe system, which is affixed to a wall at point $O,$

determine the following, What is the x$-$component of the resultant couple acting on point O$.$ Hint: add up all the x$-$components of the couples and moments. Units are taken as $[$N$-$m$]$; do not include units with your answer. Report your answer to the tenths place. The use of significant digits is not required. All forces exist solely in the principal directions.
