## anonymous 4 years ago Consider the 639 N weight held by two cables shown below. The left-hand cable had tension T2 and makes an angle of 53◦ with the ceiling. The right-hand cable had tension T1 and makes an angle of 49◦ with the ceiling.

By treating the forces in the horizontal direction separate from those in the vertical direction, we can come up with a system of equations. Horizontal:$T_1\cos(49^{\circ})-T_2\cos(53^{\circ})=0$Vertical:$T_1\sin(49^{\circ})+T_2\sin(53^{\circ})-639=0$Two equations, two unknowns, very solvable.
