Answer:
cos(2u) = 1 - 2(32°) = 1 - (2
0.281 ) = 1 - 0.5616 = 0.4384
Hence the correct option is E.) 0.4384
Step-by-step explanation:
i) 2u = 64°
ii) u = 32°
iii) sin(32°) = 0.53
iv) (32°) =
= 0.2808
v) cos(2u) = 1 - 2(32°) = 1 - (2
0.2808 ) = 1 - 0.5616 = 0.4384
Hence the correct option is E.) 0.4384
