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

Answer:
1. A Pythagorean triple
Step-by-step explanation:
B 12:3 = 4-1=3 C 10- 7=3 And A 2+15x=x=15-2=13
there are 4 aces and 4 9's for a total of 8 cards
there is a total of 52 cards
so 9/52 is the probability
