Answer:
60
Step-by-step explanation:
let's say the angle is x
tan x=2√21/2√7=1.73205...
tan inverse of it = 60
You've already correctly labeled everything you need.
-- Ignore the lines YZ and YT .
-- That leaves you with the right triangle XYW .
-- Its legs are 8 and (12+3) = 15 .
-- XY is its hypotenuse.
I'm SURE you can finish it off from here.
Answer:

P(X=1) = 1/36
P(X=2) = 3/36 = 1/12
P(X=3) = 5/36
P(X=4) = 7/36
P(X=5) = 9/36 = ¼
P(X=6) = 11/36

7/36
Step-by-step explanation:

Attached, you will find a table with the possible values of X.
(See table attached)
As we can see, there are 36 entries so,
<em>P(X=1) = 1/36
</em>
<em>
</em>
<em>P(X=2) = 3/36 = 1/12
</em>
<em>
</em>
<em>P(X=3) = 5/36
</em>
<em>
</em>
<em>P(X=4) = 7/36
</em>
<em>
</em>
<em>P(X=5) = 9/36 = ¼
</em>
<em>
</em>
<em>P(X=6) = 11/36
</em>

It can be noticed that the only possible value of X which is divisible by 4 is 4 and there are 7 entries in the table, so
P(X divisible by 4) = P(X=4) = 7/36
