4 waves $\;x_{1}=4 sin5t\;, x_{2}= 8 sin 5t\;, x_{3}=cos 5t \;and\;x_{4}=4 cos 5t \;$ interfere and if the final equation can be written in the form of $\;A sin (5t+sin^{-1}(\large\frac{B}{c}))\;$ , what is the sum of $\;A+B+C$ ?

Answer : (d) 26
The final wave is
$x_{1}+x_{2}+x_{3}+x_{4}=12 sin 5t+ 5 cos 5t$
$=13\;(\large\frac{12}{13} sint 5t+ \large\frac{5}{13} cos 5t)$
