Answer:
<h2>Side YZ is 8 units long.</h2>
Step-by-step explanation:
We can deduct form the graph that segment WO is a radius of the circle and XY is its diameters.
By given, we know that 
, which means 
, by radius definition.
An important characteristic of tangents about circles is that the tangent is always is perpendicular to the radius, that means 
and 
is a right triangle, that means we can use Pythagorean's Theorem to find the side YZ.
Where 
is the hypothenuse and 
, 
are legs of the triangle.
Replacing all given values, we have
However, by sum of segments, we have
, where 
and 
Therefore, side YZ is 8 units long.
A set that is closed under an operation or collection of operations is said to satisfy a closure
property.
For example, the set of even integer is closed under addition, but the set of odd integer is not.
(4 x 7)1/2=
length times width and divided by two is how to find the area of a triangle
The answer is 3 21/100.
