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 is $216\degree$

Carlos walked to school on 14 of the 20 school days in February. Which value is equivalent to the fraction of the school days in

BabaBlast [244]

Answer:

70%. let me break it down

Step-by-step explanation:

step 1:

14 divided by 20 is 0.7

step 2:

14/20 x 100 so we can work our way to the percentages and the answer is 70% , your probably asking, how? because 70/100 is gonna give 0.7 (7/10) so it is really similar

Question 4 Multiple Choice Worth 1 points) (01.02 MC) Solve for : 2 x - (x - 2) = 4x

oee [108]

Answer:

$\small \sf \frac{2}{3} = x \\$

Step-by-step explanation:

Solve for x;

2x - ( x - 2 ) = 4x

distribute minus sign through parantheses

2x - x + 2 = 4x

combine like terms

x + 2 = 4x

subtract x from both side

x - x + 2 = 4x - x
2 = 3 x

Divide each side by 3

$\small \sf \frac{2}{3} = \frac{3x}{3} \\$

$\small \sf \frac{2}{3} = x\: \\$
