You are given a system that is at rest; you know the **mass** of the object, and the **two angles** of the strings. In this example problem, there are two strings, one with an angle of 25 degrees, and the other with an angle of 65 degrees, and a mass: 5 kilograms. **Label the tension from the strings as T1 and T2, respectively. **

The first thing to notice is that because the system is at rest, the forces in the x and y directions balance each other out. We can now create two equations.

## Doing the Math

We now plug $T_1$ into the first equation. $$T_2 = 2.145(20.708) = \boxed{44.4193 N}$$

Now, we have our final answer. The tension in string 1 is $20.708 N$, and the tension in string 2 is $44.419 N$.
