Step-by-step explanation:
those are the multiple of 3
(1-tanx)(1-cotx)=2-secxcscx
1 - tanx - cotx + 1 = 2 - secxcscx
2 - tanx - cotx = 2 - 1/(sinxcosx)
tanx + cotx = 1/(sinxcosx)
sin^2(x) + cos^2(x) = 1
Correct question is;
Caitlin purchased a prepaid phone card for $20. Long distance calls cost 7 cents a minute using this card. Catin used her card only once to make a long distance all the remaining credit on her card is $16.8. how many minutes did her call last?
