  • Angle between vectors=180-45=135°

Now


\\ \tt\longrightarrow R=√(A^2+B^2+2ABcos\theta)


\\ \tt\longrightarrow R=√(92^2+34^2+2(92)(34)cos135)


\\ \tt\longrightarrow R=√(8464+1156+6256(-0.7))


\\ \tt\longrightarrow R=√(9620+4379)


\\ \tt\longrightarrow R=√(13999)


\\ \tt\longrightarrow R=118.3N
