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:
450 pennies
Step-by-step explanation:
2/3 ➡ 3/3 × 2/3 = 6/9
let's call it 9x
the bank contains 6x after she removes 100 pennies 4x is left
which means 2x = 100 pennies and x = 50 pennies
therefore the bank can carry 50 × 9 = 450 pennies
