For left block $T=m_1gsin(60)$...........eq(1) For right block $T=m_2gsin(20)$...........eq(2) As the two blocks are in equilibrium, so we can equate the above two equations $m_1gsin(60)=m_2gsin(20)$ This can be rearranged as: $\frac{m_1}{m_2}=\frac{gsin(20)}{gsin(60)}$ $\implies \frac{m_1}{m_2}=0.394$ $m_1=0.394m_2$ Thus, the mass of left hand block is 0.394 times the right side block.
