Answer

The force in the horizontal cord is 2900N and the force in the other cord is 3400N

Work Step by Step

Let $F_1$ be the tension in the horizontal cord and $F_2$ be the tension in the other cord. We will sum the forces in each direction to solve for the tensions. So; $(\uparrow +) \sum \overrightarrow{F}_{y} =0 $ $F_2*sin\theta-m*g=0$ $F_2=\frac{m*g}{sin\theta}=\frac{190kg*9.8m/s^2}{sin(33^{\circ})}\approx3400N$ $(\rightarrow +) \sum \overrightarrow{F}_{x} =0 $ $F_1-cos\theta*F_2=0$ $F_1=cos\theta*F_2=cos(33^{\circ})*3400N\approx2900N$
