Answer:
Below.
Step-by-step explanation:
- tan 2x = -2tanx / (1 - tan^2x)
Using the identity tan^2x = sec^2x - 1 and substituting for tan^2x:
- tan 2x = -2 tanx / (1 - (sec^2x - 1))
= 2 tanx / ( - 1(sec^2x + 2))
= 2 tan x / (sec^2 x - 2)
0.20a=220
Where 0.20 is the decimal form of 20%
a is the unknown number
0.20a=220
------- -----
0.20 0.20
a=1100
220 is 20% of 1100.
