```							Force is a vector quantity so we can add them vectorally i.e, Here f1=12 NF2= 9 NAngle= 60 degreesResultant = (f1+f2+2f1f2cos angle)^1/2                 = (12+9+2(108)1/2)^1/2                 = (129)^1/2

```							 Dear student As we know R^2 = 12^2 + 9^2 + 2 * 12 * 9 * cos 60 R^2 = 144 + 81 + 108 =333 R = sqrt(333) = 18.24 Newton Regards
