Find the angle necessary to statically balance the system by placing the center of mass on the axis of rotation for the following $2$ masses in $3$ dimensions. You are to balance the

moments about plane B by adding a mass to plane A and then find the angle that puts the center of mass on the axis of rotation. The first mr is $392$ lb $-$in at an angle of $54$ and

distance of $-5\mathrm{.}6$ inches from plane B $.$ The second mr is $438lb*in$ at an angle of $12$ and distance of $-2\mathrm{.}7$ inches from plane B $.$ The moments are to be balanced by putting mass on

plane A which is $5$ inches from plane B$.($Enter your answer to the nearest tenth of a degree.$)$
