Answer:
cos 2 x=1-sin^2 x
Step-by-step explanation:
x=-135°
cos 2x=cos (-270)=cos (-270+360)=cos 90=0
or cos 2x=1-2sin ²x=1-2(sin (-135))²
=1-2(-sin 135)²
=1-2(sin 135)²
=1-2(sin (180-45))²
=1-2(sin²45)
=1-2 (\frac{1}{\sqrt{2}})²
=1-1
=0
Perimeter is all sides added up.
So, we know the width is 19ft and the length is x feet. We also know that the perimeter is 87 feet.
What we can do is make an equation to solve for x.
2x + 2(19) = 87
First, multiply 2 and 19.
2 x 19 = 38
2x + 38 = 87
Next, subtract 38 from both sides to move 38.
2x = 87 - 38
2x = 49
Lastly, divide both sides by 2 to get the value of x.
x = 49/2
x = 24.5
Thus, the length of the rectangle is 24.5ft
We can plug it into our equation to check if its correct.
2(24.5) + 2(19) = 87
24.5 x 2 = 49
2 x 19 = 38
49 + 38 = 87
