Question 38933: solve the equation 2 sec x-5= 0 for 0 less than or equal to x less than 2 pi. give answers to the nearest hundreth of a radian. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Okay from
2 sec x - 5 = 0
2 sec x = 5
sec x = 5/2
therefore cos x = .4
and
x = cos(-1) .4
x = 1.16 radians
