Solve the equation sin2x = 3cos2x. The value of x that satisfies the equation if x lies in the second quadrant is °. The value o
faltersainse [42]

Answer:

126\degree

and

126\degree

respectively.

Step-by-step explanation:

The given trigonometric equation is

\sin2x=3\cos2x


We divide both sides by \cos2x to get,

\frac{\sin2x}{\cos2x}=3


This implies that,

\tan2x=3


We take the inverse tangent of both sides to get,


2x=\tan^{-1}(3)


\Rightarrow 2x=71.565


\Rightarrow x=35.7825

\Rightarrow x\approx 36\degree


Since the tangent ratio has a period of 180\degree, another solution is


x=180+36


x=216\degree to the nearest degree.


In the third quadrant,


2x=180+71.565


\Rightarrow 2x=251.565

\Rightarrow x=125.7825

\Rightarrow x=126\degree


The solutions are

x=36\degree,126\degree,216\degree


The value of x that satisfies the equation if x lies in the second quadrant is 126\degree


The value of x that satisfies the equation if x lies in the third quadrant is216\degree

M 1 = (2x + 28)<br> m 3= (6x + 4)<br> What is m&lt;2<br> Enter your answer in the box.
s2008m [1.1K]

Answer:

m∠2 = 140°

Step-by-step explanation:

m∠1 = m∠3, since they're vertical angles.

Solve for x:

2x+28=6x+4\\24=4x\\6=x

Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.

m∠1 = (2(6) + 28)°

m∠1 = (12 + 28)°

m∠1 = 40°

Now that we know m∠1, we can now solve for m∠2.

m∠1 + m∠2 = 180°

40° + m∠2 = 180°

m∠2 = 140°
