Three forces \(F_{1}\),
\(F_{2}\) and
\(F_{3}\) act on the
same body in the same point and the total force on the body is zero (the forces cancel). The first
two forces are \(F_{1} = 8\, \mathrm{N}\)
and \(F_{2} = 10\, \mathrm{N}\) and the
angle between \(F_{1}\)
and \(F_{2}\) is
\(55^{\circ }\). Find the
angle between \(F_{3}\)
and \(F_{1}\).
Round your answer to the nearest degrees.
\(149^{\circ }\)
\(125^{\circ }\)
\(55^{\circ }\)
\(30^{\circ }\)
