$\displaystyle \sin E=\frac{20}{101}$

Step-by-step explanation:

Recall that sine is the ratio between the opposite side and the hypotenuse in a right triangle:

$\displaystyle \sin x=\frac{\text{opposite}}{\text{hypotenuse}}$

In the given triangle, with respect to E, the adjacent side is 99, and the hypotenuse is 101. So, we are not given the value of the opposite side.

Since it is a right triangle, we can use the Pythagorean Theorem. Hence:

OU^2+99^2=101^2

Solving for OU (the opposite side) yields:

$OU=\sqrt{101^2-99^2}=20$

Therefore, the opposite side is 20.

Hence:

$\displaystyle \sin E=\frac{20}{101}$

The approximate side length of the segment WX is given by $\left[\begin{array}{ccc}2\\4.12\\4.47\\5\end{array}\right]$

The approximate side length of the segment XY is given by $\left[\begin{array}{ccc}2\\4.12\\4.47\\5\end{array}\right]$

The approximate side length of the segment YZ is given by $\left[\begin{array}{ccc}2\\4.12\\4.47\\5\end{array}\right]$

The approximate side length of the segment ZW is given by $\left[\begin{array}{ccc}8\\2.11\\1.59\\0.59\end{array}\right]$

The approximate perimeter of quadrilateral WXYZ is $\left[\begin{array}{ccc}14\\14.47\\15\\15.59\end{array}\right]$

Step-by-step explanation:

The perimeter of a figure is the distance around a two dimensional body. In other words we can think perimeter as the distance of a body's boundary.

To find the approximate perimeter of the quadrilateral, all we need to do is to add its respective lengths.

Thus here the sum of its side length gives us the perimeter of the quadrilateral WXYZ.

The approximate perimeter of quadrilateral WXYZ is $\left[\begin{array}{ccc}14\\14.47\\15\\15.59\end{array}\right]$

The approximate side length of the segment WX is given by $\left[\begin{array}{ccc}2\\4.12\\4.47\\5\end{array}\right]$

The approximate side length of the segment XY is given by $\left[\begin{array}{ccc}2\\4.12\\4.47\\5\end{array}\right]$

The approximate side length of the segment YZ is given by $\left[\begin{array}{ccc}2\\4.12\\4.47\\5\end{array}\right]$

Total sum of lengths of the three sides of WXYZ is given by $\left[\begin{array}{ccc}6\\12.36\\13.41\\15\end{array}\right]$

Therefore the value of the other side ZW is given by

$\left[\begin{array}{ccc}14\\14.47\\15\\15.59\end{array}\right] - \left[\begin{array}{ccc}6\\12.36\\13.41\\15\end{array}\right] = \left[\begin{array}{ccc}8\\2.11\\1.59\\0.59\end{array}\right].$
