If x is an acute angle and tan x = 5,
lyudmila [28]
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

Rina8888 [55]
The bicycle`s speedometer measures the speed to the nearest 0.1 mph. So 17.15 mph is not appropriate way to report speed, because then it should measure speed to the nearest 0.05 mph. Also 17 mph and 20 mph are whole numbers and it does not have to be so accurate.
