We have that
tan x=5
we know that
tan x =sin x/ cos x
sin x/ cos x=5------> squaring-----> sin² x/cos² x=25
remember that
sin² x+cos² x=1-----> cos² x=1-sin² x
substitute
sin² x/[1-sin² x]=25
sin² x=25-25*sin² x
26*sin² x=25
sin² x=25/26
sin x=5/√26
cos² x=1-(5/√26)²----> 1-(25/26)----> 1/26
cos x=1/√26
the answers are
sin x=5/√26
cos x=1/√26
Answer:
6 rides
Step-by-step explanation:
Total balance = $13.50 = ($2.25/ride)x, where x is the remaining number of rides. Dividing both sides by $2.25/ride yields 6.
Justin has enough on his bus card for 6 more rides.
The greatest common factor for 12 and 30 is 6.
