Find the perimeter of the figure to the nearest hundredth.
Alenkinab [10]

Answer: 48.84

Step-by-step explanation:

First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)

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
