Tan (x-pie / 3) = - radical 3 / 5, what is Tan x equal to?

Tan (x-pie / 3) = - radical 3 / 5, what is Tan x equal to?

tan(x-π/3)
=(tanx-tanπ/3)/(1+tanxtanπ/3)
=(tanx-√3)/(1+√3tanx)=-√3/5
5(tanx-√3)=-√3(1+√3tanx)
5tanx-5√3=-√3-3tanx
8tanx=4√3
tanx=√3/2
Tan (x-pie / 3) = - radical 3 / 5,
TaNx = Tan [(x-pai / 3) + Pai / 3] = [- √ 3 / 5 + √ 3 / 3] / [1 + √ 3 / 5 * √ 3 / 3] = √ 3 / 9
Known inequality 2 (x + 1) - 5
2X + 2-5-4, so the minimum integer solution is x = - 3, which is substituted into the equation 1 / 3 * (- 3) - M * (- 3) = 5 - 1 + 3M = 5 m = 2 m-2m-11 = 4-4-11 = - 11
How can tan (π / 2 + x) be equal to - TaNx?
Solution Tan (π / 2 + x)
=sin(π/2+x)/cos(π/2+x)
=cosx/（-sinx）
=-cosx/sinx
=-cotx
=-1/tanx
This is a formula that can be used directly. There is derivation in the textbook.
Square of the solution equation [x-3] + 4x [x-3] = 0,
(x-3)^2+4x(x-3)=0 x-3+4x=0 5x-3=0 5x=3 x=3/5
Tan (x / 2) = 2
Let X / 2 = a, then x = 2A
So tan2a = 2tana / (1-tan & # 178; a) = 2 × 2 / (1-2 & # 178;) = 4 / (- 3) = - 4 / 3
That is, TaNx = - 4 / 3

0.4x + 0.8 times (17-x) = 10, the solution is fast
I need it so much
I know that 0.4x + 0.8 times (17-x) = 10
0.4X+13.6-0.8X=10
0.4X=13.6-10
X =9
Thank you for adding 904850125 to my memorial service
0.4x+0.8(17-x)=0.4x+0.8*17-0.8x=0.8*17-0.4x=10
0.4x=0.8*17-10,x=2*17-10/0.4=34-25=9
0.4x+13.6-0.8x=10
0.4x=3.6
X=9
Answer process:
0.4x+0.8(17-x)=0.4x+0.8*17-0.8x=0.8*17-0.4x=10
0.4x=0.8*17-10,x=2*17-10/0.4=34-25=9
The result is x = 9.
0.4x+0.8(17-x)=10
Solution x + 2 (17-x) = 25
x+34-2x=25
34-25=2x-x
X=9
X=9
