At 4200, the max tax is about 2,400 so to get to 3200 raise by 800 which is 1/3
so 1/3 of 4000
or do 16.66 times 3200 which gives u about 53333.33

Solve each equation for 0° < x < 360°.

Ipatiy [6.2K]

Answer:

Hence value for x is 0 degree

Step-by-step explanation:

Given:

x limits are (0 to 360) degrees and

Cos(x+45)+cos(x-45)=Sqrt(2)

To Find:

value for X

Solution:

Given equation cos(x+45)+ cos(x-45)

Is similar to cos(A+B) +cos(A-B)=2cosA*cosB

Now comparing with general formula we get ,

A=x and B=45

Hence given equation becomes as ,

$2cosA*cosB=Sqrt(2)$

$2Cosx*cos45=Sqrt(2)$

$cosx=Sqrt(2)/(2*cos45)..........cos45=1/$ $\sqrt{2}$

$Cosx=Sqrt(2)/Sqrt(2)$

$cosx=1$

x= 0

Hence value for x is 0 degree
