So you can actually use a couple trig identities
tan(x-a) =(tan x-tan a)/(1+tan x*tan a)
From there, easy!
(tan x-tan a)/(tan x-tan a)/(1+tan x*tan a)
1/1/(1+tan x*tan a)
which is
(1+tanx*tana)
1+tan^2a
sec^2 a
typo, forgot the 1/1
Hello buddy I’m a person who knows the answer it is b
Answer:
The answered would be 1/64 since it's simplified
Answer:
circumference = 2 π r
r = 10/2 = 5inches
circumference = 2π ×5= 10π inches
option A
$4.90 Each cake cost 0.70$ so 7x7=49 add the zero and move decimal one place to left
= 4.90$
