12. the reflexive property of congruence means anything is congruent to itself
13. the transitive property of equality means if 2 things are equal to the same other thing then they are equal to each other
14. Symmetric property of equality means that you can change the order of the equation
15. That's the transitive property of congruence its basically the same as 13 but with segments instead of the measure of angles.
Answer:
21.25
Step-by-step explanation:
use the Pythagorean theorem, it is given that the shape is a rectangle so all opposite sides are congruent and all angles are right, since we know that the diagonal forms a right triangle we can use the pythagorean theorem
the Pythagorean theorm is a^2+b^2=c^2 where a and b are the legs (in this case the side of the triangle) and c is the hypotenuse which is the longest side in a right triangle
17^2+12.75^2=x^2
x^2=7225/16
now take the square root of both sides and you get -21.25 and 21.25
distance CAN NOT be negative so -21.25 isn't an option

Answer: height = 10 inches</h3>
==========================================================
Explanation:
To get the area of a triangle, we multiply the base (b) by the height (h), then we divide by 2. That leads to the value of A.
So that explains the equation A = b x h/2 which is the same as A = b*h/2
We can multiply both sides by 2 to get 2A = b*h
This flips to b*h = 2A
If we divide both sides by b, then we get the formula
h = 2A/b
The variable h is isolated on its own side.
-----------------------
Next, we'll plug in the given area of A = 60 square inches and the base of b = 12 inches.
This leads to a height of...
h = 2A/b
h = 2*60/12
h = 120/12
h = 10
The height must be 10 inches.
-------------------------
Let's check the answer
So we are given the base of b = 12 and we just found the height to be h = 10.
The area of the triangle is...
Area = (base*height)/2
A = (b*h)/2
A = (12*10)/2
A = 120/2
A = 60
Since we get the proper area, this confirms we have the correct height.

Answer:
21600 letters
Step-by-step explanation:
There are 5400 seconds in 1.5 hr, so there are 135 40-second intervals. So, 160 messages multiplied by 135 time intervals is 21600 letters.
