A vertical mast [PQ] is supported by two sraight cables [PS] and [PR]. The cables are joined to level ground at S and R where |SR| = 15cm. |RQ| = 17.4cm and |\n" ); document.write( "
\n" ); document.write( "-----------------\r
\n" ); document.write( "\n" ); document.write( "tan(50 degrees) = PQ/RQ = PQ/17.4
\n" ); document.write( "So, PQ = 17.4*tan(50) = 20.74 cm
\n" ); document.write( "----
\n" ); document.write( "sin(50) = PQ/PR
\n" ); document.write( "PR = 20.74/sin(50) = 27.07 cm
\n" ); document.write( "-----
\n" ); document.write( "SQ = ?
\n" ); document.write( "tan(PSQ) = PQ/SQ = 20.74/?
\n" ); document.write( "====================
