#ANSWER#
(1+sinx/cos²x) =tan²x+1+tanx . secx
-> [(1+sinx/cos²x)] = 1/cos²x+sinx/
-> cos²x
-> = sec²x+tan x sec x
-> =tan²x+1+tanx secx

Answer:
x=7
y=13
Step-by-step explanation:
Let kenyan fresh roast=x
And Sumatran coffee=y
x pound +y pound=20 pounds
x=20-y
Cost
x cost $11
y cost $10
11x+10y=10.35*20
Substitute x=20-y into the equation
We have,
11(20-y)+10y=207
220-11y+10y=207
-y=207-220
-y=-13
y=13
Recall
x=20-y
Substitute y=13 into it
x=20-13
x=7
