Use the identity
sec^2x = 1 + tan^2 x
- so sec x = sqrt(1 + tan^2 x) then:-
tan x + sqrt( 1 + tan^2 x) = 1
sqrt ( 1 + tan^2 x) = 1 - tan x
1 + tan^2 x = 1 + tan^2x - 2 tan x
0 = -2 tanx
tan x = 0
x = 0, π
π is an extraneous root because sec 180 = -1
So the answer is 0 degrees
Answer:
The value of the expression is 80.
Step-by-step explanation:
14 - 6 = 8.
10 x 8 = 80.
All you have to do for each question is do (population times growth, the answer of that times 25 plus the original population and that’s 2025 population.
