Your answer would be 7.94 units.
First we must note that a perpendicular bisector halves the side it is bisecting, so FA = FB. This then allows us to say that FA = 9, as 18 ÷ 2 = 9.
Now that we know FA = 90, we can see the right triangle with a hypotenuse AD, which is 12, and a leg FA, which is 9.
This then allows us to use Pythagoras's Theorem to find a leg of a right triangle, c² - b² = a², so we can do:
12² - 9² = 144 - 81 = 63
√63 = 7.93725, which is 7.94 to the nearest hundredth.
I hope this helps!
W is 38 to form a right angle
Z is 29 for the same reason
Y is 52 because of vertical angles

Well, if this wasn't the question please explain to me what I'm answering!
The theoretical probability of an event is the likelihood that the event will occur. It is calculated by finding the ratio of the number of favorable outcomes to the number of total outcomes. In probability, the total outcomes are the total number of possible outcomes for the probability experiment. (Paraphrase this answer so you don’t get caught for plagiarism)
