Additional formula:
sin (theta + π) = sin (theta) · cos π + cos (theta) · sin π =
= 0.3 · ( - 1) + cos (theta) · 0 = - 0.3

To solve this question, first find the value of theta.
Sin (theta) = 0.3
Theta = sin^-1 (0.3)
Theta = 17. 457 degrees.
Pi = 180 degrees.
Sin (17.457+180) = sin (197.457) = - 0.3.
