What is the magnitude of the resultant force between 142 N and 215 N, forming an angle of 112 degrees

[From: ] [author: ] [Date: 12-04-19] [Hit: ]
......
c^2 = a^2 + b^2 - 2ab*cos(C)
c^2 = 142^2 + 215^2 - 2*142*215*cos(112)
c^2 = 20164 + 46225 - 61060*cos(112)
c = sqrt(66389 - 61060*cos(112))
c =~ 298.7682690547568655616493425962
