we have the function

5\cos x-5=0

Rewrite

\begin{gathered} 5\cos x=5 \\ \cos x=\frac{5}{5} \\ \cos x=1 \end{gathered}

The domain for x is the given interval [0,2pi) ----> 2pi is not included

the values of x are

x=0 radians

<h2>The solution is x=0</h2>

ella drew a rectangle that was 3 units wide and 4 units long. Draw a different rectangle that has the same perimeter but a diffe
RUDIKE [14]
First we can find the perimeter of the given rectangle

P=2L+2W (L=length and W=width)
P=2*3+2*4
P=6+8
P=14

So now we want to come up with a different combination of numbers that would give up a perimeter of 14. We know that 14 is divisible by 2 so let's make out width 2. If we plug in 2 as the width and 14 as the perimeters, we can solve for length

14=2L+2*2
14=2L+4 
10=2L (subtract 4 from both sides)
L=5

So the dimensions are 5 units and 2 units

Hope this helps!

olasank [31]

42°

Step-by-step explanation:

\angle BAE =180\degree -132\degree

(Angles in linear pair)

\angle BAE =48\degree

\angle AEB =90\degree..(\because \overrightarrow{EC}\perp\overrightarrow{ED})

\angle ABE = 180\degree-(48\degree+90\degree)

(Angle sum postulate of a triangle)

\implies\angle ABE = 180\degree-138\degree

\implies\angle ABE = 42\degree

\angle CDE =\angle ABE = 42\degree

(corresponding angles)

\implies x\degree=\angle CDE

(vertical angles)

\implies x\degree=42\degree

\implies x=42
