<span>Use the Pythagorean theorem for the right triangle

where

is the hypotenuse of the triangle;

and

are the other two sides.
So,

AC= √CD^2+AD^2
AC= √AB^2+BC^2
Those two are true

You're pretty much screwed
Given:
Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.
To find:
The graph that represents the set of heights that satisfy this requirement.
Solution:
Let x be the height required for the ride.
Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.

So, 54 and all values above 54 are in the solution set.
Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.
Therefore, the correct option is C.
It is true that 3=4 times 3\4 because 4 times 3 equals 12 while 12 divided by 4 equals 3.
3=3 is true.
