To find the answer we can calculate the values independently first:
Cos 35 = 0.8192
Cos 85 = 0.0872
Cos 155 = -0.9063
Therefore;. Cos 35 - cos 85 + cos 155
Will be ;. 0.8192 - 0.0872 + ( -0.9063)
= 0.8192 - 0.0872 - 0.9063
= 0.1743
Cos 35 = 0.8192
Cos 85 = 0.0872
Cos 155 = -0.9063
Therefore;. Cos 35 - cos 85 + cos 155
Will be ;. 0.8192 - 0.0872 + ( -0.9063)
= 0.8192 - 0.0872 - 0.9063
= 0.1743
