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.
Answer:
y < 4

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard. Scientific notation is a way of writing very large or very small numbers.

Step-by-step explanation:
FInd the height of the box by dividing the volume by 7 x 5 ( length x width)
Height = 105 / 35
Height = 3cm
There are 6 sides to a box.
Surface area = 2 x length x width + 2 x length x height + 2 times height x width
SA = 2*7*5 + 2*7*3 + 2*5*3
SA = 70 + 42 + 30
SA = 142 cm^2
