Answer:
8.7 cm
Step-by-step explanation:
You know the relationship between the diagonal of a rectangular prism and the sides as
where x, y and z are the three dimensions of the prism. from your data,
or
. With some simple calculation you get
, or 
145=10x-8x it’s A I’m pretty sure
Answer:
Option 2
Step-by-step explanation:
y=x+3 is a positive slope so the line going up to the right is a positive slope and the line passes through y-intercept at 3
The answer is 13.
Because this is a kite, the diagonals intersect perpendicularly or with a 90° angle.
In the triangle DIC, which is a right triangle, the legs are 5 and 12. To find the hypotenuse, we use Pythogarean theorem:

Plug in the givens:

Take the squares:

Take the square root of both sides:

We find the line segment DC. In the question it says "BD = DC". So BD is equal to 13.
