A mass is suspended from three strings as shown in the below figure. The ceiling of the room has length $x=4\mathrm{.}3m$ and width $y=2\mathrm{.}1m,$ and the string B is connected $l=0\mathrm{.}8m$ from the corner. The length of the strings are $A=3\mathrm{.}1m,B=2\mathrm{.}3m,$ and $C=2\mathrm{.}3m$

Problem: Calculate the tension in each string.
