Answer 2

Answer:

Formula to be used

=-=-=-=-=-=-=-=-=-=-=-=

= > \bf \: \sin(180 - x) = \sin(x) \\ \\ = > \bf \: \sin(180 + x) = - \sin(x) \\ \\ = > \bf \: \sin(360 - x) = - \sin(x)

__________________________

= > \bf \sin(24) + \sin(55) - \sin(125) + \sin(204) - \sin(330) \\ \\ = \sin(24) + \sin(55) - \sin(180 - 55) + \sin(180 + 24) - \sin(360 - 30) \\ \\ = \sin(24) + \sin(55) - \sin(55) - \sin(24) - (- \sin(30) ) \\ \\ = \bf \: \sin(30) = \frac{1}{2} = 0.5
