Select a statement which is NOT alternative form (NOT common translation) of a given statement. " If I do logic puzzles, then it drives me crazy"

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
