Step-by-step explanation:
the answer is on the pic above
27%=27/100
so 27/100=81/x
27x=8100 divide by 27
x=300
that the answer
Step-by-step explanation:
∫ (sec x − tan x) dx
∫ sec x dx + ∫ -tan x dx
∫ (sec²x + sec x tan x) / (sec x + tan x) dx + ∫ (-sin x / cos x) dx
ln(sec x + tan x) + ln(cos x) + C
