Brainly do your thing i need help

Zolol [24]

Answer:

x=56

Step-by-step explanation:

As ∠FAC and ∠EAD are vertical angles, the measure of their angles must be the same. This means that ∠ $A=60$

Now, we can use the fact that the line EAC would have a measure of 180 degrees.

Due to this, we can add up all of the angle on one side of that line to find x.

$60+64+x=180\\\\124+x=180\\\\x=56$

Answer:

General solution is

$x = n \pi + \frac{\pi }{8}$

Step-by-step explanation:

Step(i):-

Given cos x - sin x = √2 cos (3 x)

Dividing '√2' on both sides , we get

$\frac{1}{\sqrt{2} } cos (x) - \frac{1}{\sqrt{2} } sin (x) = \frac{\sqrt{2} cos (3 x)}{\sqrt{2} }$

we will use trigonometry formulas

a) Cos ( A + B) = Cos A Cos B - sin A sin B

b) $cos \frac{\pi }{4} = \frac{1}{\sqrt{2} }$

Step(ii):-

$\frac{1}{\sqrt{2} } cos (x) - \frac{1}{\sqrt{2} } sin (x) = \frac{\sqrt{2} cos (3 x)}{\sqrt{2} }$

$cos (\frac{\pi }{4} ) cos x - sin(\frac{\pi }{4} ) sin x = cos 3x$

$cos (\frac{\pi }{4}+x ) = cos 3 x$

Step(iii):-

General solution of cos x = cos ∝ is x = 2 nπ+∝

we have $cos (\frac{\pi }{4}+x ) = cos 3 x$

The general solution of $cos (\frac{\pi }{4}+x ) = cos 3 x$ is

⇒ $3 x = 2 n \pi + (\frac{\pi }{4}+x )$

⇒ $3 x- x = 2 n \pi + \frac{\pi }{4}$

$2x = 2 n \pi + \frac{\pi }{4}$

final answer:-

General solution is

$x = n \pi + \frac{\pi }{8}$

Same solution as 2(x+4=-7-3x

Bas_tet [7]

Answer:

x = -3

Step-by-step explanation:

2(x+4)=-7-3x

Distribute

2x+8 = -7-3x

Add 3x to each side

2x+3x+8=-7-3x+3x

5x +8 = -7

Subtract 8 from each side

5x+8-8 = -7-8

5x = -15

Divide each side by 5

5x/5 = -15/5

x = -3
