Answer:
The ratio for sin(X) is 
The ratio for cos(X) is 
Step-by-step explanation:
- The ratio of the sine of a right triangle is:

Since we need the ratio for angle X,
. From the picture we can infer that the opposite side of X is
. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:

- The ratio of the cosine is:

Similarly,
, adjacent side = 5, and hypotenuse = 12, so

X=2 or -7(answer choice A)
38 chose rock .. it’s in the problem. Hope this helps :))
Answer:4
Step-by-step explanation:
Let a denotes the no of odd ball selected and b denotes the no of even ball selected
then 
for 
for 
for 
for 
thus X can take 4 values i.e. 9,10,11 and 12
